nah, go 48v if your drives can support it. its the current which matters. You could drive the motors at 72 volt with the right drivers if you wanted and still not break them,

the cheap drives i got are only rated for 42V so i am looking to run them on 36v, this is going to be on the cheap side for builds. i don't do things as pictured by others i just use it for a starting point for planning. i plan on using double shielded wires everywhere with shield drains on everything. i have spent a lot of time reading up on grounding and a lot of it was plasma related for a source. i have seen way too many builds get sideways because of grounding issues

the Nema 23 motors i picked up and dives were only $110 for 4 so nothing very fancy. THCAD is about the cheapest height control on the market, so being able to do that makes me happy

i'm not ready to buy boards from Mesa just yet and the THCAD-300 is out of stock at the moment, and it is a little bit cheaper than the THCAD-2 so with added cost of having to buy extra stuff with shipping on top of that saving $20-$30 makes me lean towards the THCAD-300 just because i am cheap

you put me on the right track.....
I was provided with the vendor ID (0x4321) and product ID / code (0x10C2) by the manufacturer. 
And these values show in the drive through the software also

using the below terminal input
ethercat slaves -v

the product code was 0x00d0   ???

can anyone provide the reasons for this ? please remember the internal drive value is what the manufacturer stated !

i made this change to the .xml and the drive works.

There is QtTouchy available in linuxcnc as well.

It connects to the hardware stepgen index pin
probably something like:

hm2_7i96s.0.stepgen.00.index-enable

halcmd show pin hm2 | grep index
 (when linuxcnc is running)

should list it

Hello,
im struggling with the modification of qtdragon. I just replaced 2 buttons. Im able to use the new design and works almost everything well. The 2 new butttons are not working. I tried with the costum_postgui.hal but i got always an errror that this pin is not valid.So i checked in qtdragon via hallshow which pins are avalibel and i didnt found my button (action_air). i searched everywhere but i dont find anything like that. (Not even action_flood and that is working well)I wanted to search for the iocontroll but that is a executable file and i cant open it. (well, im not that familiar with linux).

I hope someone can help or give me some suggestions.
