Using Spotting with Sheetcam

I am going to try spotting some hole with sheetcan and PlasmaC.

In sheetcam I made a tool number 2 and ran the post then in the gcode it looks OK with the parameters the same as in the manual.

I think I may have read somewhere that you need to have the tool number in the linuxcnc tool table is that correct?

No thats for scribing. Just make a tool in Sheetcam called CENTRE SPOT and do a drilling operation with it.

Thanks Rod, This is the gcode just for a test . The test_1 is with the rotary tool and test_2 is when renamed the tool to centre spot.

Would you mind confirming if " test_2 is correct "

If using the PlasmaC.scpost then there two methods of spotting:

1. You can use the CENTRE SPOT (CENTER SPOT) tool - you need to ensure that you made the leadin for a circle start at the centre as the spot is made at the start of the leadin.

2. You can use a drill operation using any tool.

The code looks OK assuming the spots are in the correct place.

With the code above the torch does not fire. What am I missing?

Looking in the Lcnc tool table I see only 2 tools 0 and 1

Did you enable the multiple tools in the <machine_name>_connections.hal?

Change

setp plasmac.multi-tool 0

to

setp plasmac.multi-tool 1

Yes, the offsets for the scribe tool are handled in the linuxcnc tool table. You can change it by editing the tool.tbl file in the <machine_name> folder.

Yes I have setp plasmac.multi-tool 1

Edit I looked in the tool table there is only 2 tools But I can't edit it as it is a sim link

LinuxCNC tool #0 is the torch and toll #1 is the scribe (if you have one) Spotting uses tool #0

Do you have multi tool enabled in your <machine_name>_connections.hal

Have you set the threshold volts and delay time in the config panel.
