Re: Can Centroid Control this?
Can Oak run without this encoder feedback? No. Neither can Heidenhain, unless all it does is move back and forth between limit switches. What exactly is a "Gate machine"? If the Heidenhain control had a DRO position display, and the ability to move to programmed positions, then there is p...

Re: Acorn won't run g code/mdi < lathe G98/G99?>
His Ahha programs will not run without some changes.
G90 is not appropriate there. All X and Z coordinates are absolute by default.
"F8" looks like an inches-per-minute feedrate. To use that, you need a G98 code.

Re: Acorn won't run g code/mdi < lathe G98/G99?>
Have you tried G98, as Keith suggested?
For example:
... or, if you are going to use G1 in the default G99 mode, do you have the spindle running already, and have you given it a suitable per-revolution feedrate?
For example:
For example:
Code: Select all
G1 G98 F5 X1 Z1
For example:
Code: Select all
M3 S1200
G1 G99 F0.01 X1 Z-2

Re: Can Centroid Control this?
You can probably run that system with Oak (+OpticDirect) in analog velocity mode. The drives need the tachogenerator feedback from the motors, to do their speed control. The Oak needs quadrature position feedback to know where the axis is. No, there is no way to usefully generate a quadrature encode...

Re: mpu11 machine
Short answers: (1) The CNC program you posted, written out by the "mpu11wheeldig.txt" file currently on your control, assumes that PLC bit MEM72 (CNC variable #70072) will indicate when dry run mode is active. However, your PLC program sets MEM58 (CNC variable #70058) to indicate dry run m...

Re: Hardinge CHNC4 Retrofit
You could use the OpticDirect interface through the DriveBus connection on Allin1DC. OpticDirect can run third-party drives in either analog velocity mode or in position mode. You are not guaranteed synchronized movement with the Allin1DC axes if you use position mode, but for basic functional testi...

Re: Enable outputs on Acorn
I agree with Nigelo. Foremost, your emergency stop circuit should remove power from the stepper drivers. That should reliably ensure that the motors are free of power and torque whenever emergency stop is pressed.

Re: Issue with outside frame milling
The Intercon program and graph are correct. It is tracing around the outside of a 2" x 3" rectangle, centered at X1 Y1.5. The toolpath (cutter center) is correctly offset to the outside by 0.1875 (the radius of the cutter you specified). Assuming that you did your part setup so that MDI &q...

Re: Issue with outside frame milling
Okay, let's revisit your original description of the issue. The tool path will be off in both the X and Y directions but not in both plus and minus directions. Is the frame that the tool traces: 1) Too large or too small in X and/or Y? 2) Off center in X and/or Y? It would help if you would post a c...

Re: Issue with outside frame milling
This is likely an error setting your Part Zero location.
After you have set your X and Y axis part zeros, then jog Z just clear of the surface, and use the F3/MDI prompt to run:
Does the tool (spindle centerline) line up over where you thought you set part zero?
