Re: [Emc-users] BLDC on 7i43 + 7i39 + linear motors

Wallace p...@mesanet.com написав: What I am asking is if the 7I39 encoder inputs work normally now If not, this still suggests a wiring error of some kind I test only X axis now. The encoder is connected to 1 (A) and 3 (B) wires of ribbon cable, and it works on X axis. The cable connects 7i43 (P4) to 7i39. The motor is connected to bottom right connector on 7i39, from bottom to top: Ground, U, V, W. Top left corner orange LED on 7i39 lights, as well as bottom green LED among 5. When I start the machine, the middle orange LED of 5 lights too. I guess 7i39 receives power well. Absolutely no idea what can be wrong. BTW manual shows 1+5 leds but only 5 described.

Re: [Emc-users] machine shop advice
At least I can open up the stl files and view them in 3-D. There are several areas that are impossible to machine... they could be injection molded but not machined. Sharp inside corners in the Z axis are not machinable... if they have a radius they can be machined. The smaller the radius the longer it will take to machine as the tool would be small.

Re: [Emc-users] Hardinge HNC
Yes, I'm ssi on IRC, and the conversion was quite straightforward. I have $400 in Mesa gear, under $200 for two vfds, and miscellaneous wiring supplies. The stock resolvers work great with mesa's 7i49, there's no problems with the Hiak amps. The only issue I ran into was dirty tachs, and they cleaned up easy enough. Conversion took about 2 weeks of evenings.

Re: [Emc-users] machine shop advice
It appears that all the hexes have sharp inside corners as well as a couple of places on the inside of the base. The bosses around the screw holes on the top inside corners are drawn sharp inside corners. The middle section bosses for the screw holes also have sharp inside corners. I wish SolidWorks would do more with the stl file than just create an image of it in one color with no edges... I had to google bromine to see what that is...

Re: [Emc-users] machine shop advice
The only places that require a 1/16 bit are the o ring grooves on the base and middle pieces. Everything else ended up with 1/8 radius. I machined the radius with a ball end mill, which is time consuming, but less than doing it by hand. The base this fits in was machined using a ball end, so to fit I have to radius the bottom. Here is what mine http://aercon.net/Public/Image40.jpg looks like.

[Emc-users] the state of the Wiki
Gentle persons: When the dust settles over some of the recent, long threads on subjects like G540 Test Update and BLDC I hope the essences of the subjects get distilled into useful pages on our Wiki. Speaking of the Wiki nudge, nudge, wink, wink, it could use a lot more editorial work. Looking at the Recent Changes listing, I see the usual few suspects making progress but there is a lot of work left. Back in January, after the decision was announced to rebrand our work LinuxCNC, I spent time under my SourceForge pseudonym CNCDreamer trying to fix up the most egregious instances of EMC2 but had to leave a number of pages marked as in progress because they required technical changes I felt unprepared or even unqualified to make. Looking now, I see many of the same pages haven't been touched since. There are a number of pages that are terribly stale and the organization of the home page is trending toward chaos. Try to read it like you were new to LinuxCNC and see what you make of it. I wish I were in a position to do more of what needs to be done, but recent challenges at home make a concerted effort impossible. I'm lucky to have time to skim the mail-list traffic and I have a bunch of projects that haven't progressed beyond acquisition of parts. Come on, jump in, the water's fine.

Ayway, just in case here it is: http://www.wallacecompany.com/cnc_lathe/HNC/emc2/nc_files/M111 and I guess you simply haven't finished it yet, it's a copy if M110...

Re: [Emc-users] Fw: machine shop advice
Its not pure bromine. Its just enough to make some plastics brittle. Its in tablet form, so it is probably an occasional 10% ?? liquid? Why the fuss over pvc? It machines ok for me. Its much better than uhmw.

There are several areas that are impossible to machine... they could be injection molded but not machined. Sharp inside corners in the Z axis are not machinable... if they have a radius they can be machined. The smaller the radius the longer it will take to machine as the tool would be small. I can only view a stl file and can't make a solid out of it... Is there some reason you selected PVC as the material? From a plastics manufacturer: . Materials that are resistant to bromine are few: titanium, fiberglass reinforced plastic (FRP) and PVDF. PVDF was considered the best choice because vessels made of FRP have been known to blister and fail prematurely, whereas titanium is very expensive. From Cole-Parmer database: Listed as very good; viton, pvdf, teflon, noryl, kel-f, hastelloy-c. Ti was listed as poor. Another source listed stainless steel but did not recommend Ti No one listed glass which is absolutely resistant to bromine but not much of an engineering material. Clearly YMMV. Good luck.

Their prices were better than FirstCut for 5-days turns, while FC was better for 1-3 day turns. With FC and RM, they used my exported STEP 214 files from Alibre. With FC, I use their online system to call out the threads. With RM, I had a separate .pdf calling out my threads.

BLDC motor won't rotate when connected to DC, unlykely to brushed DC motor. But it jerks, that's enough to see it's OK. In my case it's HIWIN linear DC motor, it just moves to a certain point when connected to DC. What are you hooking the encoder to? What kind of encoder is it?

Re: [Emc-users] BLDC on 7i43 + 7i39 + linear motors
You don't need an Oscilloscope to determine if your power supply is faulty, also you can check to continuity of all your wires using a simple multimeter. Keep it simple. Again what kind of Encoder are you using?

Wallace p...@mesanet.com написав: Flat cable problems? The fact that the encoder inputs on the 7I39 do not work for you means something is wrong either on the 7I39s or the interconnections to the 7I43 The cable is probably OK. I bought 2 of them and no one works. And the cable uses 2 completely pairs of wires for encoder 0 and 1. Very unlikely that all these wires damaged. And some kind of signal was going to 7i43, so they're can't be broken. The same with 2 7i39s, none of 2 do not work. Something might be wrong with the power supply from 7i48 to 7i39, but the power LED is on, and when I connect 7i48 to the same 7i43 with the same cable - all OK. Feels like I'm stuck completely, at least till my oscilloscope arrives (maybe 2 weeks). Also feels like both 7i39 might be damaged - in the worst case. 17 квітня 2012 р. 16:28 rob c crob...@live.ca написав: So the 7i39 is a brush less DC motor, if your trying to see if the motor it self is functional just hook it up to a DC power supply, 12V would do just fine, if it rotates regardless of polarity the motor is good and you need to move onto the electronics. BLDC motor won't rotate when connected to DC, unlykely to brushed DC motor. But it jerks, that's enough to see it's OK. In my case it's HIWIN linear DC motor, it just moves to a certain point when connected to DC. What are you hooking the encoder to? What kind of encoder is it? It's linear incremental quadrature encoder, connected to MESA 7i39 card (dual 3 phase bridge driver for brushless 3 phase motors). Andrew -- Better than sec?

Re: [Emc-users] C Compiler - MPLAB
Dave wrote: It is just a little overwhelming what can be done with these ARM MCUs. Yes, I'm using the Beagle Board in some projects. One of them receives TCP packets and sets a 32-in 8-out signal multiplexer in a location that is sometimes inaccessible due to radiation. It is a totally minute application for such a powerful processor, but it was extremely easy to set it all up, since it runs a COMPLETE Linux kernel with X, Ethernet, compilers, etc. The hard drive is a 4 Gb SD card. I had never developed a TCP server before, I downloaded a few sample programs off the net and had a working server running in one day. The entire program, including setting up the OMAP CPU's GPIO ports as I needed them, setting up the server and binding it to the TCP port and converting incoming packets to settings of the multiplexer is all less than 3 pages of C code! Another project that is in the development stage now is a multi-channel counter/ratemeter that will have a Glade interface accessible through an ssh -X connection. The Beagle Bone has even more features and costs less! Jon -- Better than sec? Nothing is better than sec when it comes to monitoring Big Data applications.

Re: [Emc-users] the state of the Wiki

Looking at the Recent Changes listing, I see the usual few suspects making progress but there is a lot of work left. Back in January, after the decision was announced to rebrand our work LinuxCNC, I spent time under my SourceForge pseudonym CNCDreamer trying to fix up the most egregious instances of EMC2 but had to leave a number of pages marked as in progress because they required technical changes I felt unprepared or even unqualified to make. Looking now, I see many of the same pages haven't been touched since. There are a number of pages that are terribly stale and the organization of the home page is trending toward chaos. Try to read it like you were new to LinuxCNC and see what you make of it. I wish I were in a position to do more of what needs to be done, but recent challenges at home make a concerted effort impossible. I'm lucky You're very persuasive--this sounds like a useful project that I'd like to help. Can you make a list of pages that require most urgent update, in your opinion? to have time to skim the mail-list traffic and I have a bunch of projects that haven't progressed beyond acquisition of parts.
