Mach4 General Discussion / Re: How do I get to the center of 2 edges?

« on: October 10, 2017, 05:50:08 AM »

The button code needed is simple. Here is what I used for X/2; Y*2 is similar:

--AW. Halve X axis position for centring
local inst = mc.mcGetInstance()
local val = mc.mcAxisGetPos(inst, mc.X_AXIS)
local rc = mc.mcAxisSetPos(inst, mc.X_AXIS,  (val / 2))

You might want to set EnableWithMachine for these buttons.

Faced with this same issue I added X/2 and Y/2 buttons to the offsets tab. These behave exactly as per a physical dro and divide the axis dros by 2.

Has anyone tried the latest 3.02 release of the CSMIO plugin?

Just interested as I wait impatiently for the IP/A version to appear.

Glad you got it working. I find that this combination generally works well with my CSMIO-IP/A but it can sometimes freese Mach4 during probing cycles. When Mach4 freezes, the probe does not move, so there is no chance of damage to it.

If you need to revert to plugin 2.910, it might be worth winding Mach4 back to version 4.2.3233. I use the IP/A but find that 2.910 is incompatible with newer versions of Mach4 than 3233, so the same may apply to the IP/S.

After mulling this over in the shower, I don't think that the Work Shift would satisfy your need, as I think it would be nullifies each time you subsequently touched off.

So if you cannot move your work zero within the CAM program, why not just do the obvious and set your X and Y  DROs to your tool radius instead of zeroing them at touchoff. For example if you touch off at the south west corner of your stock using  a 10mm cutter, you would set each DRO to -5.0

Your lower image appears correct, but I'm not seeing their relevance.  You need to look at paragraph
3.5 on Fixture Offsets.

Just go to the Diagnostics tab, enter your cutter radius into the Work Shift fields for X and Y, and see if it does what you want. You may need to experiment with the signs depending where you touch off on the work.

You can enter them either directly into the Fixture Offsets table (View menu) or via the Diagnostics tab. See the Operations manual for a brief description of their effect.

I haven't used them myself, but would Work Shifts give you a way to correct this?

Global variables declared in the screen load script are indeed visible to the PLC and will retain their values as you require.
