home built plasma table

[wilkies]

needing help with new home built plasma table,any one here can explain why this torch will turn on with g-code m03 and the screen switch,but wont shut off with either the mo5 or switch?.thanks dave

[motoguy]

Whatbrand plasma cutter are you using? What control software?

[urbnsr]

There are plasma cutters that have a switch: CNC or Manual. Depending on this selection, it may take a second M03 to turn it off.

the software is sheetcam and mach3 how do i try or check the mo3 twice .for on and off

[wilkies]

the cutter is a colossal tech

[tcaudle]

What turns on or off and where is determined by the mapping in MACH3 (Ports & PIns) Mapping for M commnads on outputs is in Ports & Pins / Spindle swettings int he M codes section. they define with M codes does what to which ouput. Outputs in MACH are numbered 1 - N (most BioB only support 1 to 3 ) and . That will be up to your interface electronics . You should be abkle to manully test your on/off ouput by manully jumpering the two wires that fire your torch. Shorting the piar should fire the torch. Removing the short should turn it off

i can load a g-code program it will home z then set o material, go to cut height,m03 torch on, cut path,at m05 torch stays on ,moves to next cut with torch on. im at a loss here

How do you have the plasma interfaced to your controller? On the off brand models most guys interface with the hand torch switch.
Is that what you did? Also how are you getting Arc OK feedback?
Google your plasma machine and didn't really see anyone machine cutting with it.

[wilkies]

yes its hooked from the torch held switch conected to the spindle relay on the tb6560 controler,it has a floating head,with proma thc. it will run a complete g-code program with out the torch on,with torch on it will run, just wont torch off.dave

[wilkies]

my torch switch wires are hooked to the mon and min on the controler for spindle (i think its the relay),could i have the wires reversed.there is also a 0-10v /pwn input interface for spindle has grd and pwn. any ideas welcomed. dave

[sphurley]

TB6560 is a Toshiba chip used on boards. What brand/ model of controller do you have? Min and Mon don't sound like a relay. (which is what you need)

[wilkies]

ok go to ebay type in tb6560 then find the new 3 axis cnc stepper motor driver tb6560 set+led display+handle controller(there are many),some show the relay and some hookups and settings.need anyone to help me out on this. dave

the first sheetcam processor i used was one with a scriber and in the g-code it had m03 for torch on and m05 for scriber on,could this have changed the setting in mach3 if so can anyone explain how to correct it. dave

Hi Dave
Only a suggestions,
If you got this through e-bay, why not send the question to the supplier.
They would be the best people to ask.

Not sure again, but what post processor are you using when you generate the code in SheetCam, is it a plasma option
maybe again the supplier might be able to help selecting the right one for the kit you have

[sphurley]

Look at pin 3 of the DB15. Put an ohmeter on it and ground and see if that works. The Mon Min are for the 0-10volt VFD control.

[wilkies]

the are like you guys they dont know any thing about it they just sell them!

[wilkies]

sorry dont see pin3 on a db15

[wilkies]

im now using mp1000 with thc. dave

M05 has never been used un a MACH based POST to turn on or off a scriber. IT ALWAYS is used to turn OFF an M03/M04 ON command. Scriber onis either m07 or m08 (aka Flood and Mist) and M09 turns BOTH of them off

[wilkies]

if mo5 turns m03 and m04 off then what can be wrong with mine mach3 g-code m03 turns the torch on,it makes no since why m05 will not also shut it off

[wilkies]

ok on closer look the relay sticker the torch is hooked to says relay m1 and m2 beside that is also two hookups output / grd and 0-10v

[wilkies]

looks to be the plasma cutter is to blame,the points are sticking on the torch on/off in the plasma cutter. thanks for the help dave ps it is a relay and is working with m03 and m05
