The Borg Collective of LinuxCNC must be busy ... so only one mind is responding via this email...;-) 40 gigs is plenty. I think you will find that after you install everything you can think, and do a git clone to setup a RIP, you will still have way over 30 gigs of drive space left. Dave

Hi everyone After three weeks I've got the latency down under 10,000 and received and installed my breakout board. Now I'm trying to get it going. With unipolar stepper motors and 2 wire uln2003 stepper drivers need to alter the to 5,5,5 or 6,6,6 , the step and direction to A- and B+ , and remo

Hi, I have some problems in setting up BLDC servos, I just don't manage to get enough torque. Here's the set-up: Intel D525MW Mesa 5i23 Mesa 7i39-LV Nanotec DB57L01 + 4000 CPR endoder The servos are rated 24V DC, 4.6A (peak 17A). My power supply is 24V DC SNT rated at 500W. I suppose I j
