Modbus / MPG help...
« on: February 14, 2014, 08:22:42 AM »
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?

Rule #1... Anything bought off the internet from China there is a 50/50 chance it won't work right or will work for very long.
Rule #2... Don't expect instructions that make sense or customer technical assistance.
Rule #3... Good luck getting a refund. Most of the Chinese sellers make claims to warrantee products but trying to collect on that is almost impossible.   
Rule #4... Yes, it's cheap but you get what you pay for.

Most MPG have the ability to program the function buttons and usually come with software for that purpose. Unless you have the software or instructions that make sense, you are probably out of luck.

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 :)

It will most likely just be a configuration issue, with the button mapped to wrong Mach function.

How is the pendant connected, and do you know how it's communicating with Mach (i.e. is it emulating a keyboard, or does it have it's own plugin, or someway else?)

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.

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

Got a link to one?
