Re: Home to limit switches.

I am not sure why your homing macro has "L2" with each M91 or M92 command. Usually an Acorn would use "L1" there, so that CNC12 does not try to back off to the encoder index pulse (which is not available, with Acorn). Try changing the "L2" to "L1" and see what...

Re: Hardinge CHNC II+ Hickory LeadShine EL7 Retrofit

Yes, in early probes like this one, the probe-detect jumper was just installed in the 8-pin plug. In later probes like the DP4 and KP3, that function was moved into the probe body itself, so that the probe would not be "detected" if the cord alone were plugged into the control's probe rece...

Re: Homing 4th Axis

Jog the A axis until INP6 is green. Then press Cycle Start to find home.

Re: Homing 4th Axis

Your cncm.hom file has only an M26 for the A axis. It has no M92 to move it to its switch. You have correctly indicated that INP6 is a fourth axis home switch, and it shows up in your Machine Configuration -> Motor Parameters table as such. You have correctly indicated that you want to home your A a...

Re: "Z compensation" on 4x8 foot CNC router

As an example, what would the compensation files look like for a router-like machine with a 10" x 10" work envelope, with a bowl-like depression in the table? In this example, more Z- compensation is needed at X5Y5; less Z- compensation at X0Y5, X10Y5, X5Y0 and X5Y10; and no Z- compensatio...

Re: "Z compensation" on 4x8 foot CNC router

I do not have time to review the volumetric compensation manual for you in detail right now. With luck, cnckeith or someone else who has worked with it can comment. But... I do not think that volumetric compensation, as currently proposed, will do what you want. If I understand it correctly, it woul...

Re: Control Panel Circuit Protection

Yes, that is most typical.

Bring a ground wire in along with your AC service lines, and land it on a panel/cabinet ground lug adjacent to where the incoming power is connected. Then run a wire from there to whatever terminal block you want to use to collect the rest of your grounds.

Re: NEW Atrump Retrofit Project.

If I were doing it, and I had reason to believe that the existing DC servo motors and encoders were in good working order, then I would use an Allin1DC, plus a DC1 drive for the fourth axis, plus a PLCADD1616 board for the additional I/O required by the tool changer. That would be a fairly major cab...

Re: Tool offset library in param's ??

Tool offsets are not in the Machine Parameters table with Parameters 0 - 999. Tool Offsets are accessible as CNC system variables, #10000 - #10200 and #11000 - #11200. See section 11.2.16 of the Mill operator's manual (page 193 in the 1/11/24 PDF version). Tool offsets can also be set using the G10 ...

Re: Macro Help For Floating Z- Soft Limit

Your original plan should also be workable, assuming that "#53 04" was really meant to read "#5043". If you are going to auto-measure a tool so that its length offset might change, you should do that, and activate the new offset, before you inspect variable #5043. You should add ...
