So i converted my CNC to arduino and grbl. The problem i have is that on short distance x and y travel are of by a few mm.
Lets say on 60mm it cuts 64mm, but on a 120mm cut, its dead on120mm.
If it was the other way around id understand. Makes no sense to me…
- $132=200.000 (z max travel, mm)
- $131=200.000 (y max travel, mm)
- $130=200.000 (x max travel, mm)
- $122=10.000 (z accel, mm/sec^2)
- $121=10.000 (y accel, mm/sec^2)
- $120=10.000 (x accel, mm/sec^2)
- $112=500.000 (z max rate, mm/min)
- $111=1000.000 (y max rate, mm/min)
- $110=1500.000 (x max rate, mm/min)
- $102=1030.000 (z, step/mm)
- $101=120.390 (y, step/mm)
- $100=120.390 (x, step/mm)
- $27=1.000 (homing pull-off, mm)
- $26=250 (homing debounce, msec)
- $25=500.000 (homing seek, mm/min)
- $24=25.000 (homing feed, mm/min)
- $23=0 (homing dir invert mask:00000000)
- $22=0 (homing cycle, bool)
- $21=0 (hard limits, bool)
- $20=0 (soft limits, bool)
- $13=0 (report inches, bool)
- $12=0.002 (arc tolerance, mm)
- $11=0.010 (junction deviation, mm)
- $10=3 (status report mask:00000011)
- $6=0 (probe pin invert, bool)
- $5=0 (limit pins invert, bool)
- $4=0 (step enable invert, bool)
- $3=2 (dir port invert mask:00000010)
- $2=0 (step port invert mask:00000000)
- $1=25 (step idle delay, msec)
- $0=10 (step pulse, usec)
- $$
