[Emc-users] Motion King Motors
I have been reading the emails concerning these motors. I recommended these motors and we have used about 40 of them without a problem. We are using them with our own pcb utilising the AMC DZR servo amplifier modules. I would agree that your motor cables should be about 1.5 mm sq and be covered with an overall screen connected to ground at the servo amplifier end. The motor encoder and hall cables should also have an overall screen connected to ground at the servo amplifier end. One problem I did not fully appreciate was the current drawn by the two 26LS31 line driver integrated circuits mounted on the motor pcb and consequently the volt drop over the cables we were using. Have you measured the voltage on the pcb in the motor ? When we experienced peculiar numbers of encoder counts being measured by our servo amplifier we discovered we had only 4.75 volts at the motor end. Increasing the supply voltage so that we had 4.9 volts at the motor end cured the peculiar encoder counts.

Re: [Emc-users] linear scales Heidenhain
If you want an in-expensive way to convert Heidenhain 11uA analogue sine wave current output scale signals to TTl then Google 'IC Haus'. They do an evaluation board for their chip 'iC-NV' which with the addition of 2 resistors will convert sine to square with interpolation values upto 16.

The controller doesn t work any more. I have read something about retrofitting. The most people use the Mesa cards in combination with Linuxcnc. For already a few years (no time like everyone) I a bought a Heidenhain EXE 935 convertor ( 3 axis from sinus wave to ttl signal) . The moment I bought these EXE 935 the Mesa 7i49 didnt exist . In my opinion I have two options : Mesa 5i20 + Exe 935 + 7i33 and 2 x 7i37TA Mesa 5i20 + 7i49 + 2 x 737TA Which are the advantages or disadvantages to use the EXE 935 ?? I prefer without (the more I use the more can stop working) Are You sure that linear scales have analog output? I was offered to do a retrofit of Maho MH400P mill, so few months ago I spent few hours going through a thick file of documentation and I remember that I saw something about quadrature TTL signal. I did not pay that much attention to it, because I was looking for instructions how to remove the cover from hydraulic pump. It needs to be fixed and that is a prerequisite for me to get that job. Is there any chance that You have some useful information about servicing hydraulic pump of Your mill?

So, how about a small current transformer around one of the wires leading to the real fuse? Their consistency is good enough the power folks drive their usage meters from them at the heavier load sites. That then needs a way to get it into the machine via a spare pin on the cnc2pc C1G card.

Re: [Emc-users] Small servo motors
Viesturs, When I was looking for brushless servo motors with hall effect and encoder I looked at Anaheim but also found a company called Motionking. I am sure the Anaheim motors come from China where as Motionking is the english supplier of a Chinese motor manufacturer called Apex Motor Company. The Apex motor website is all in Chinese script ! We have used about 40 of these Chinese motors which we have wound with our own Ke of 20 volts 1000rpm. We have used these motors on our own machines using the Advanced Motion Control DZRALTE amplifier modules on our own pcb. You can have the Motionking motors customised to your own requirements and delivery is about 3 weeks. If you Google Motionking motors and look through to BLS motors you will find the information you need. http://www.MotionKing.com sa...@motionking.com Media Lee is the contact Regards, Tim James ITP Group UK --Original Message-- From: Viesturs Lācis To: Enhanced Machine Controller (EMC) ReplyTo: Enhanced Machine Controller \(EMC\) Subject: Re: [Emc-users] Small servo motors Sent: 1 Sep 2012 13:00 Hello!

I would appreciate, if You could share some sources of small servo motors. I would prefer something that matches 7i39LV drive.

Re: [Emc-users] OT: 3D Printer Mods?
I am involved with the automotive design industry and 3D printers are used extensively for the manufacture of small parts for full size and scale automotive models that cannot be machined from clay..

While I fully appreciate the value of the learning, especially for children, people using EMC are perforce versed in CNC milling. Yes, can I ask 3D printer owners to share the practical use of those prints? Ok, I see that lots of different stuff can be made, like that Eiffel tower, which would be real PIA to manufacture with mill (if that is possible at all). But that is just a toy. And then it was mentioned that different sculptures (at least that is how I understood it) can be printed out. But also that is some decorative stuff... Is there any practical use of 3D prints? Can it be useful to make something like cases for MPG pendants or something else? That is why I asked about the properties of material. If it is elastic and bouncy, then I do not see lots of practical applications... If it is hard, but very brittle, then IMHO it is troublesome too. I just would like to understand, if it is something more than just look, how nice is this. -- Viesturs If you can't fix it, you don't own it. http://www.ifixit.com/Manifesto -- Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.

[Emc-users] Live CD
I have downloaded and burnt the Live CD 10.04. It has worked on one desktop I tried but not on another or my laptop. I only have the laptop with me at the moment so I would like to install Ubuntu and EMC to find out more in conjunction with reading all the EMC manuals I have printed out. The laptop is a Panansonic Toughbook CF29,Windows XP,Pentium 4,756Mb ram. From the users emails over the last few days I tried the ctrl/alt/f1and have experimented with the f6 boot options. The laptop appears to boot to a certain point and then the screen goes blank and then 'hangs' with the power off button being the only option. If I delete splash-- and replace it with vga=771 then the display remains on and the laptop 'hangs' on pulseaudio configured for per-user sessions line. I have tried some of the other f6 suggestions but not all as yet (I will wear the power button out soon). I don't know if I can add the options sequentially to the boot line or only use one at a time. Does anybody have any suggestions rather than me working through all the f6 options without really knowing which maybe causing the boot problem ?
