When i cut out a square that is 50x50 mm the machine acts great.
But if i do a cutout on 600mm x 600mm the first pass seems to do good, next run it for sure have missed some steps. and it goes worse and worse.
Iam not sure what this could be. when i let the machine go without the spindle it will do the whole gcode without any hickups.
More details please. Zip and include your Gcode. It is usually speeds 99% of the time but you haven’t given any other information to go off of. Build pics, bit, spindle, material, size, diameter, rapids vs cutting?
Ok here is some info, the gcode is from aspire, i used the file number 5 seems to work on the minor things. like the 50x50mm square that is made right before i tryed the 600mmx 600mm cutout.
I have tried 50mm/sec with 3mm cut, and i think the last one is 25mm/sec 2mm cut.
Could it be stepperdrivers that is to hot? and miss steps?
Its a ramps 1.4 with the recomended stepperdrivers and the recomended voltage on the steppers. followed the instructions on the build.
Material trying to cut is ordinary plywood.
its a 4mm 2 flute bit.
Okay wait, I jumped the gun, I should not make blanket statements. What leadscrew are you using, what steppers, drivers, control board, firmware, and step rate?
Have you tried using my crown gcode with great results?
