ive been finally making use of my g540 enabled kx1 machine, and ive run into an odd issue.
my x and z axis seem to randomly stall for a few moments during a program run. doesnt happen every time, but maybe once every 2 or 3 runs. ive confirmed its not a cutting load issue as it does it with no work piece on the table as well.
i had the thing tuned rather well, and its NEVER onece stalled while jogging. ive lowered the acceleration to nearly 1/2 and at first i thought it helped, but i hasnt. doesnt seem to have decreased the frequency of the stalls.
i also tried turning off the machine and restarting after the motors have cooled, thinking perhaps it was a heat issue. no help there.
to note, its only stalling in single axis moves.
as might be remembered im in 1/2 step mode due to microstepping losing steps at low speeds. my step/driection timings in the tuning panel are 0/1. the core mach frequency is 100000hz. cpu load is 60%. also mentioned in the past, im on a 19.5v psu which is just above the limit.
any thoughts on what i should try to tweak first?
i have a hunch that is could be voltage spikes in the psu dropping below the geckos limit momentarily and thus stalling the motor. no spikes show up ever on the volt meter though and i dont know if this is what would happen in this situation anyway.
ive ruined like 10 work pieces today! whaaa!
its ok, was just scraps of pine.
