Hello everyone!

I have a strange problem with PCBGCODE and LINUXCNC. When I generate a drill file with eagle and PCBGCODE, everything seems fine. But when I go to run it in LINUXCNC it spits out "Need tool prepared -Txx- for toolchange"

Now what the heck could that mean???

I created a drill rack file for pcbgcode:
T01 0.3mm 0.000mm 0.350mm 1.5in
T02 0.4mm 0.351mm 0.450mm 1.5in
T03 0.5mm 0.451mm 0.550mm 1.5in
T04 0.6mm 0.551mm 0.650mm 1.5in
T05 0.7mm 0.651mm 0.750mm 1.5in
T06 0.8mm 0.751mm 0.850mm 1.5in
T07 0.9mm 0.851mm 0.950mm 1.5in
T08 1.0mm 0.951mm 1.050mm 1.5in
T09 1.1mm 1.051mm 1.150mm 1.5in
T10 1.2mm 1.151mm 100.00mm 1.5in

And my tool table file for LINUXCNC:
T1 P1 Z0 D.3 ;.3mm PCB Drill Bit
T2 P2 Z0 D.4 ;.4mm PCB Drill Bit
T3 P3 D.5 ;.5mm PCB Drill Bit
T4 P4 D.6 ;.6mm PCB Drill Bit
T5 P5 D.7 ;.7mm PCB Drill Bit
T6 P6 D.8 ;.8mm PCB Drill Bit
T7 P7 D.9 ;.9mm PCB Drill Bit
T8 P8 D1 ;1mm PCB Drill Bit
T9 P9 D1.1 ;1.1mm PCB Drill Bit
T10 P10 D1.2 ;1.2mm PCB Drill Bit

I am reluctant to use the "simple drill code" because I don't want to miss out on any features PCBGCODE has to offer.

What could be happening? Thanks in advance!

I thought it might help if I posed my gcode:

Shouldn't the tool command be issued earlier? I think you should move it:

Looks to me like it's ok. It moves z to 2mm (my clearance height), then it bring it to the home position, then spindle on (why???), then a dwell to let it spin up, then spindle stop, then z up to 25.4mm, then the tool change. It all makes sense to me, asides from the spindle on for no reason. What is it that you see in the code that makes you think it should be higher up? Thanks for the reply BTW, im so confused...

I was guessing that you've had a command that needed a tool and I didn't check for one. Like said, guessing.
But after some googling - it is actually the top hit in the search for "linuxcnc Need tool prepared" - I think I know your problem. Your post processor is making several M06 without a T-parameter. Remove those lines or adjust them to correct settings.

For reference, this thread is the first hit by Google.

I had seen that post but I assumed that since there was an initial M06 WITH a T parameter that the rest would work. I'll try removing all the M06s without the T param and let you know how it goes. Thanks!

And know?
