Something about a cam on a tensioned wire IIRC. Being an old curmudgeon ( is that redundant?) I just have to ask what the precision of the process is if the bed were perfect? Maybe I envision the tooling plate incorrectly but why wouldn't one that was simply flat do. After all you do have a controllable Z axis. Despite claims by various people about resolution to .01 mm or so it still comes down to the accuracy and precision of the process. On another tangent I wonder about using a polynomial (curve fit) but with the number of inflections points you have it may be pretty high order. Linear interp instead of a continuous function may still be best. This is the kind of thing that starts email wars. ;-) Best wishes however you decide to cure the problem. Dave Dave, If the bed were perfect, I wouldn't need a correction factor for the Z axis. ;-) I need to keep the finished cross-section to + or - .001 at each 1 X station. 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!

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 wendt.m...@gmail.com To: Enhanced Machine Controller (EMC) emc-users@lists.sourceforge.net Sent: Wed, 19 Nov 2014 08:17:31 -0500 Subject: Re: [Emc-users] Screw Mapping On Wed, Nov 19, 2014 at 8:12 AM, p...@wpnet.us 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?

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.

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 wendt.m...@gmail.com To: Enhanced Machine Controller (EMC) emc-users@lists.sourceforge.net Sent: Wed, 19 Nov 2014 08:57:53 -0500 Subject: Re: [Emc-users] Screw Mapping On Wed, Nov 19, 2014 at 8:49 AM, p...@wpnet.us 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.

Hi Rick. It looks good as field I/O using the Modbus Protcol (with Classic Ladder I/O scanning or mb2hal component as well) . The price is pretty good for the US market and it is industrial grade hardware fully certified.

2014-11-19 10:26 GMT-03:00 Jeff Epler jep...@unpythonic.net: this thread has a reverse-engineered pinout for ZP1. http://www.cnczone.com/forums/mazak-mitsubishi-mazatrol/77549-mitsubishi-tra41-servo-drives-interface-help-please-2.html as you might have expected, it looks like the amp is analog velocity input. http://innovative-rc.com/tra41.jpg Andy's PDF shows resolver feedback. Both Mesa and Pico have solutions for analog servo amp + resolver feedback that work nicely with LinuxCNC. That forum discussion pretty much solves all my doubts. 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.

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. Less than 1000 within a year or two I believe. Anyone here interested in doing this little project? I can prepare the mold layout, I can generate the tool paths too.

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 petefro...@gmail.com: 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.

2014-11-19 21:44 GMT-03:00 robert - Innovative-RC rob...@innovative-rc.com : hi looks the same servos as on the M0 which is a machine i retrofitted, its a Mill but the same deal check the linuxcnc forum i put alot of info on the drives on there when we did our retrofit with the old DC servo drives... if you need to know anything else let me know ill try and help the best i can... what is the melda control model? or more so what are the servo drive numbers i might have a manual of sorts rob Hello Rob and thanks for your interest in helping me! 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?
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 project.tux...@gmail.com: 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 -- Download BIRT iHub F-Type - The Free Enterprise-Grade BIRT Server from Actuate!

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 petefro...@gmail.com: 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. It might be able to be built in other ways as well but it sounds like you have a good bit of knowledge in that arena. I see you have several MadCam videos online that looks interesting have not seen or heard much about it.

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. Less than 1000 within a year or two I believe. Anyone here interested in doing this little project? I can prepare the mold layout, I can generate the tool paths too.
