Mach3 supports IJK in abs or Inc mode. G91.1 sets Mach3 to Inc IJK's

In the safetly line you may consider cancelling ALL offsets  you need to add G49  and setting the G54 at that point as well. Also set the IJs to INC just to be safe G91.1 .

The rest looks OK from here.

General Mach Discussion / Re: How to set up Mach3 so that B Axis controls rotation of the mill head

« on: January 04, 2015, 04:29:05 PM »

Mach3 does not do kenematics so you do NOT have world point jogging of the B axis. As to the setup to generate Gcode that would be UP TO the CAM program You would have to have a 4/5 axis CAM and setup the axis offset there so it KNOWS how to generate the proper geometry for the part and tool  offsetting.

Just a thought, (;-) TP

Is  X the long axis or short axis on your machine ?

Are you using metric or imperial values for setup ?

Do you have the specs on the motor you are using as to power requirements Volt, Amps ?

Do you have the Drives set to the proper AMPS for the motor ??

Do yo have a picture of your machine ?

LazyCam (Beta) / Re: incremental I and J not working

Within Mach3 it does NOT matter if you use INC or ABS IJs as LONG as both programs ( Cam and Controller) are set to the same mode.

The default POST in Lcam should be set to INC and seems to output INC IJs.

IT is YOUR job to make sure they do not get them mixed up in your Gcode.

It is NOT a good idea to use the G28 and G90 on the same line. IF you were to use a way point in the G28 it may NOT go to where you expected to go.

Your G90 would BEST be placed in the safety line (N1 in your case) which defines how Mach3 is to act on startup of the File. The G90 sets Mach3 to (ABS) mode for motion. Then IF you need to switch over to G91(INC)you call it as needed.

In you code example you have a mixed  code call  with the G28 Z0  G91. You would normally never want to do a G28 in INC mode as it may never complete the motion. Remember you are creating a POST for MACH3 NOT Fanuc so you have to play by Mach3 rules.

For a simple 3 axis machine the LPT version works just fine. No outside controller needed. THC for the plasma works fine as well.

Do you have a tensioner on the wrap wire ??

When you get a complete set wound send them over for a good testing (;-)  I am due for a new set here .
