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 to
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.

Change

Code:

setp plasmac.multi-tool 0

to

Code:

setp plasmac.multi-tool 1

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

You shouldnt have to anyways, I apologize, I read scribe (theres still coffee to be drank in the pot), for spotting as Phill said, it uses the same offset as the torch.

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