Anyone using xyotech controller boards? I’m having issues with my stepper motors stalling out. Having to keep my Rapids really low, and have to watch my machine like a hawk to catch any issues and reset my x,y,z zeros.
xylotex?
add dampers to the stepper shafts, hopefully you have dual shaft steppers.
you can make one out of a hockey puck.
do a search and you will see many examples.
Will look into this, I bought this as a big of a basket case, mach3 wasn’t setup, so I had to figure out all the setup from scratch, and I’m realizing that while I have it running its waaay slower than what is often needed for decent cutting speeds and the Rapids really cause slow downs in producing parts. Will try the hockey pucks as they are cheaper than the Gecko drive conversion I’m contemplating.
what is your power supply voltage? I think xylotex is 36v max?
chances are your steppers inductance rating is too high for your power supply voltage. Add that to the lack of mid-band resonance compensation of the xylotex, and you have slow and unstable rapid speeds.
you can make what you have work, but gecko’s do give a very nice boost with 48v and correctly matched steppers, versus a random pieced together kit.
Cheers Alan, that looks like a simple enough experiment. Will look into the inductance, it has always “worked” but I think my friend just kept his Rapids below the mid band resonance, so this things rapids were set at 15 ipm. Should be able to get up to 40 within reason based on my 280oz in motors and 30V power supply.
Hard to believe but three 99c Hockey pucks seem to have helped out a bit. I may modify the pucks by drilling a ring of pockets around the circumference and adding some weights that can move slightly, for damper 2.0. But ultimately I think I may be asking a bit to much from my current setup.
