I just finished building the C-Beam XL machine...it was a great experience. Nice job on the bundle and build descriptions. Moving on to the electronics setup and tining is where we started to run into problems. Components.... DQ542MA drivers, Nema23 high torque motors, Xpro v3 controller, meanwell power supply 24v, all parts from Openbuilds...etc I've made it past the initial setup issues on my own, but now I'm stuck and need the help of experts. One of the y axis motors isn't consistently turning at the same rate as its counterpart motor on the Y axis. Initially I though it was due to the two y gantry rails not being parallel to each other and causing a bind as it traveled. I verified the rails are in fact parallel and even with the table taken off the 2 y axis gantry plates, the gantry plates will occasionally travel different distance. Sometimes they travel the exact distance in sync, other times they don't. Does this problem give any of you out there an idea as to where I should start the troubleshooting?
