I recently finished putting together my CNC router using the Beaglebone Black, a 5 axis breakout board, HY-268-N6 drivers, and NEMA23 steppers. Since I received assistance with getting my steppers moving in the correct directions (my earlier post on this forum), everything works great for jogs. I can jog any axis at 120 in/min without problems. The issues come when I try to run a gcode file through it. No matter how slow I set the feeds, it seems like I get following errors. I've googled the issue and tried:
1. Increasing the min_ferror and ferror values (up to 0.5/1). 2. Decreasing the pru_period to 5000. 3. Increasing or decreasing the DEFAULT_VELOCITY and MAX_LINEAR_VELOCITY values. Goal is for a max of 120 in/min but plan to run around 25-50% depending on what I'm working on. 4. Increasing or decreasing the MAX_VELOCITY and MAX_ACCELERATION for each axis (although it seems like the y-axis is usually the one giving me errors). I've been keeping the stepgen values 20-25% higher than the max velocity/acceleration values. 5. I adjusted the microstepping to lower the steps per inch scale value. Didn't seem to make any difference. I'm currently at 1/2 stepping I believe. 6. I've played with the driver timings (DIRSTEP, DIRHOLD, STEPLEN, STEPSPACE) but they didn't seem to change much. The values are high due to the cheap drivers I'm using but they work just fine when jogging... Any thoughts? I've still got my configuration files at the following links (ignore the hal_bb_gpio values - I've corrected the pins since posting the files): Xylotex.hal: https://pastebin.com/UNtgPpyx Xylotex-axis.ini: https://pastebin.com/u5Ba6ULH Xylotex.postgui.hal: https://pastebin.com/NFHf6Px9 Thanks for looking! ~Matthew -- website: http://www.machinekit.io blog: http://blog.machinekit.io github: https://github.com/machinekit --- You received this message because you are subscribed to the Google Groups "Machinekit" group.
