Re: [Emc-users] OT: US member doing injection molding?
I'm located in the far far West. Hawaii. @John: I have a 50 ton injection molder and I started making a new one but smaller that I was going to control with an Arduino. The CNC machines are one bug steel frame router table and a retrofitted operation center. Both are servo driven. I would love to help but I guess you are on mainland. @Ron: Thanks for the tip, will look into that. /S 2014-11-20 2:53 GMT+01:00 Tux Lab : > Hi Sven, > > Where are you located?

I was trying to find your posts on the forum but there are so many that I can't. Can you point me to the post if you remember the name of it? or may be your user name on the forum?. The control of the machine is a Mazatrol T1. The servo motors are Mitsubishi, and the drives are Meldas. The servo drives model numbers are TRA-31A and TRA-41A. The main concern for me is how to set up the connection to run the drives with LinuxCNC. From what I could read, it seems that if I let everything as it is, and run the drives with the ready signals and the analog voltage for the velocity they should turn. The tachos will be telling to the drives the actual speed and I would only have to close the loop on LinuxCNC using the resolvers. I guess it's not more difficult than that. But I would love to hear suggestions! -- *Leonardo Marsaglia*. -- Download BIRT iHub F-Type - The Free Enterprise-Grade BIRT Server from Actuate!

Re: [Emc-users] OT: US member doing injection molding?
Hi Sven, Where are you located? What kind of milling machine were you controlling with LinuxCNC? I am sort of meandering my way toward setting up a domestic manufacturing cooperative and am contemplating building a LinuxCNC control milling machine.We are also sort of working our way toward getting a small 25 ton injection molding machine up and running. If you are near by, is building a LinuxCNC control mill something you are interested in? thanks, John tux-lab.com On Wed, Nov 19, 2014 at 4:25 PM, Sven Wesley wrote: > Hi Pete, > > This part requires injection molding and a UV-resistant plastic.

Re: [Emc-users] OT: US member doing injection molding?
Sven, Thanks for the well thought out explanation I have not seen much of MadCam maybe I need to investigate further. Good luck in your search. If you had needed the part machined from solid stock I may have been able to help but I do not have plastic injection molding capabilities her. Good luck in your search.

Re: [Emc-users] OT: US member doing injection molding?
Hi Pete, This part requires injection molding and a UV-resistant plastic. I would like to do it in PC due to it's durable properties but that's a tough plastic to work with so I'm willing to use something else, PET would probably work too. I do have some knowledge. My workshop has injection moulders and several CNC machines for mold making. MadCAM is a plugin for Rhino 3D that can make everything up to 5 axis simultaneous. The LinuxCNC Post processor included in the application is my fault. :) It's not for free though, but compared to the other competitors I think there is no one who can compete with the features in that price range. And the lead developer is a well experienced guy in tooling so he is not just a programmer, he has both an injection molding company and a tooling workshop under his wings. I would guess 15 employees doing this kind of things all day long. Unfortunately this project is a bit too small for them in quantity figures. 2014-11-20 0:43 GMT+01:00 Pete Matos : > Sven, > Perhaps if you can post a photo of the part or the cad drawing people > could be able to give you a better idea of who and how to make it.

Are you looking for someone to make the mold, do the molding, or both? I know a local guy who is good for small runs of molded parts, but he isn't equipped to make very complex molds (2.5D cnc, manual milling and turning, sinker EDM).

Anyone of our members making plastic parts? I have a small piece I want to make a few hundreds of, but since I moved to the US I have no access to a workshop and my own workshop is shut down and closed until I decide to move back. It's an end cap to a mirror mount, transparent, not big but a little bit complex shape. I would have made the tool in aluminium (like Alumek) as the quantity will not be super high.

Re: [Emc-users] i guess i need a new motherboard for new linuxcnc
I'm using the M5A78LM LX V2 model from ASUS with AMD processor and behaves really great. Good latency results, although I'm using hardware for steps generation. I don't know if the same version is still on sale, may be there are newer versions of the same mother called V3 or so. 2014-11-19 16:52 GMT-03:00 : > Can you all recommend a basic motherboard that is know to work with > LinuxCNC running a parallel controller?

So, until the motor is moved to the index position, there would be no absolute angle indication for commutation. The AD chip gives absolute angle output which we bring out to a header, so an additional board could be put in to generate the commutation signals from that. But, it would need to know the number of motor poles and the angular offset. So, such a board hasn't been designed. If enough people needed such a feature, we could come up with it.

It seems the driver uses tacho generation to close the speed loop within itself, and the only signals I need to replace are the analog voltage for the velocity command and some of the ready and fault signals to make it work. Also the pin information is a great help to start testing. I'm not sure about one thing in the pictures of my drivers and it's the fact that there's a connection between the two of them, I'm going to see if I can find out something on my PDFs but I'm not sure about what that might be for. I'm planning on use the resolvers as you suggested since they work really great and also everything is already mounted so practically I don't have to touch anything of the mechanical units. I hope I can do some testing soon because replacing the original control will give me a lot of new functionalities.

There's an interesting section there about how to tune the parameters using the presets on the driver. I think I saw something like that in one of the PDFs that I have, I don't know if it's the same.

Re: [Emc-users] Something of Interest
Most of my LinuxCNC installations include a PLC and I usually
communicate to them via Modbus RTU (serial) or Modbus TCP.
So far I've used Siemens, AB, and Automation Direct PLCs with LinuxCNC.
I have always used CL to do the Modbus interface. It works!
CL can do Modbus registers, inputs, outputs, and internal coils.

Re: [Emc-users] Something of Interest
I've used a fair amount of Automation Direct hardware, and have always found their quality to be good, their pricing to be good, and their customer service (including tech support) to be excellent. Mesa Electronics sells an excellent remote I/O solutions that work almost exactly the same way. They're not as modular, but the price is less, it needs only power and a Cat5 cable to communicate to the Mesa Electronics board in the main panel (even though it's not Ethernet protocol). The Mesa Electronics solution is well supported in LinuxCNC. http://www.mesanet.com On 11/19/2014 09:13 AM, Rick Lair wrote: > Not sure if this compatible or not, but I was just perusing thru > Automation Directs web page, and noticed this.

Hi Rick. It looks good as field I/O using the Modbus Protcol (with Classic Ladder I/O scanning or mb2hal component as well) .

Re: [Emc-users] Screw Mapping
Perhaps a reducer bushing would be needed to adapt the center hole size. Precise centering wouldn't be a big deal since you'd be dressing the wheel to profile in-place inherently centering it. I suspect it would be cheap enough to be worthwhile even if you still used a correction table to get things exactly perfect. Mechanical precision is generally better than electronic compansation since issues such as axis acceleration can come into play when trying to correct for mechanical issues. --Original Mail-- From: "Mark Wendt" To: "Enhanced Machine Controller (EMC)" Sent: Wed, 19 Nov 2014 08:57:53 -0500 Subject: Re: [Emc-users] Screw Mapping On Wed, Nov 19, 2014 at 8:49 AM, wrote: > Smaller dia grinding wheels have higher max RPMs, and it looks from the > machine pics like the saw blades are pretty small diameter so a grinding > wheel in their place would be similarly small.

Hard part would be holding the grinding wheel in the spindle. The spindle is a built-in saw mandrel, and the saw blade fits just snugly over the male insert portion of the mandrel.

Re: [Emc-users] Screw Mapping
Smaller dia grinding wheels have higher max RPMs, and it looks from the machine pics like the saw blades are pretty small diameter so a grinding wheel in their place would be similarly small. The necessary wheel is probably $20 or so. I also think the offset correction table is probably workable, but it's nice to have things as mechanically perfect as possible to start with. --Original Mail-- From: "Viesturs LÄcis" To: "Enhanced Machine Controller (EMC)" Sent: Wed, 19 Nov 2014 15:36:28 +0200 Subject: Re: [Emc-users] Screw Mapping 2014-11-19 15:17 GMT+02:00 Mark Wendt : > On Wed, Nov 19, 2014 at 8:12 AM, wrote: > >> How about temporarily replacing one of your saw blades with a grinding >> wheel, dressing it to the correct angle to be flat across the width of the >> vacuum table and then light grinding passes down the table?

Re: [Emc-users] Screw Mapping
I'm not a grinding expert, but I believe it would work fine with the correct selection of grinding wheel type. A quick look on www.nortonindustrial.com shows many wheel compositions recommended for grinding aluminum. I bet a call to one of their application engineer folks would get you a good recommendation for a wheel in the size and material you need. Grinding doesn't have to be terribly high RPM, your 4,000 should be fine, it's more a function of taking very light cuts and not letting heat build up. --Original Mail-- From: "Mark Wendt" To: "Enhanced Machine Controller (EMC)" Sent: Wed, 19 Nov 2014 08:17:31 -0500 Subject: Re: [Emc-users] Screw Mapping On Wed, Nov 19, 2014 at 8:12 AM, wrote: > How about temporarily replacing one of your saw blades with a grinding > wheel, dressing it to the correct angle to be flat across the width of the > vacuum table and then light grinding passes down the table?

How about temporarily replacing one of your saw blades with a grinding wheel, dressing it to the correct angle to be flat across the width of the vacuum table and then light grinding passes down the table? Your saw spindles should be plenty rigid and high enough RPM, and dressing an angle on the grinding wheel is easy with a diamond dresser. --Original Mail-- From: "Mark Wendt" To: "Enhanced Machine Controller (EMC)" Sent: Wed, 19 Nov 2014 07:25:11 -0500 Subject: Re: [Emc-users] Screw Mapping On Wed, Nov 19, 2014 at 7:20 AM, wrote: > Is there a way to clamp a sander or similar to the head for use in > flattening?

Is there a way to clamp a sander or similar to the head for use in flattening? A solid clamping and a series of light cuts ought to flatten to match the axis. --Original Mail-- From: "Mark Wendt" To: "Enhanced Machine Controller (EMC)" Sent: Tue, 18 Nov 2014 10:56:10 -0500 Subject: Re: [Emc-users] Screw Mapping On Tue, Nov 18, 2014 at 10:32 AM, dave wrote: > > On 11/18/2014 06:45 AM, Mark Wendt wrote: > > Stuart, > > > > I have no tooling plates in use now. ;-) > > > > Mark > > > > > Hi Mark, > > I don't know if the site is still active but Les Watts used an > interesting compensation > scheme for his router.

I'd have to rebuild the machine to use some kind of tooling plate. The "table" is actually my vacuum hold-down. I have no way to "cut" the table flat using the machine itself, unlike a router. The cutting head is made up of two saw blades held at an included angle of 60 degrees, with the "point" of the "V" at the bottom. I've tried to flatten the bed by filing, sanding, etc, but the problem is, I really have no reference to the cutting head. That's how I end up with being 2 or 3 thou low in one area, 3 or 4 thou high in other areas and so on. I've shimmed out the table as best as I can, and this is what I'm left with, so I'd like to correct for the Z using some kind of compensation read into the machine. Be a lot easier to do it once, rather than having to do it each time I create a different G Code file for each different rod and each different section. I like Andy's lincurve idea. I just have to go through all the reading of the suggestions given this morning, and work out how I can apply it to my machine. I think lincurve will probably be the simplest approach. -- Download BIRT iHub F-Type - The Free Enterprise-Grade BIRT Server from Actuate!
