I'd guess it's using the serial modbus.

Got a link to one?

It's eBay item. 231030701972

Hi
It uses the serial port plus a USB port, I think the USB is used for power.

It uses the macro pump feature in mach for the jog wheel afik.

There is no driver and no software, couldn't even get the manual to download but there were so many identical clones on the net I just copied the simple setup procedure.

No worries, I got it off eBay so a refund is guaranteed.

I was hoping an easy fix was possible but never mind, i was doubtful it would even arrive in the first place

I'll try asking the supplier, should be fun

As a bit of entertainment I ordered a super cheap handwheel pendant off ebay to connect up to my plasma table (which is still being assembled  ), surprisingly it arrived today after only two weeks.

Anyway, got it set up and seems to work apart from one bit which makes no sense and i'm not sure if it's the super cheap pendant or a setting I need to tweak.

When I jog the head to where i want to start, I presumed I press the button marked "Origin" also labelled as "Start Point" in the chinglish manual and then press "Start"?

But when I press "Origin" it presses the Mach3 "To Go" button on screen and does not set start coordinates so when i press "Start" it starts at machine zero.

Is this fixable or should i stop messing about and return it for refund?

Ver .066 is the worst release ever and should be avoided.

That's the one I'm running

Config menu then Safe Z Setup,  see if you have it enabled.

Well it was set to zero in m/c co-ords which should have been ok but i set it to -25 just to be sure.

Makes no difference, it pauses ok but when restarted it just lifts the Z into the upper soft-llimit and sits there, pressing start again simply starts the cut with the Z at top-zero position!

When the pause is pressed, why can't it..
1 - Store the current parameters - X, Y, Z, Torch status etc
2 - Stop at the end of the current line
3 - turn the torch off
4 - Lift the head
5 - wait

When resume is pressed...
1 - Return to the last X, Y position
2 - Lower the torch and detect z position again,
3 - Turn the torch on
4 - Resume cutting at the last coordinates

Obviously there will be a bit of plasma muck where the torch was turned off / on but seems a reasonable tradeoff for stopping mid-cut?

Yes I home all three axes, unless it's a default, I can't remember setting a safe z axis??

I'm trying to figure out how to temporarily stop a program running on my plasma table.

I know all about the big red button but that's not ideal if i just need to pull a tip-up out the way etc.

I have tried the Feed-Hold (space bar) feature and it does stop it running but as soon as i hit cycle start to get going again, it just raises the Z-axis into the soft-limit and all action stops.

Am i thinking of the correct method or can you not simply hold a program.

I have my z-limit at the top and I'm using soft-limits as well and G31 for the height probe on my floating head.

Thanks
