Re: M200 prompts sometimes disappear

Regarding corbin's initial application: There is already a well-defined place on the screen for status updates, to tell the operator what the machine is doing as it runs. That is the scrolling message box in the upper right. Floating message boxes in the middle of the screen are an appropriate place...

Re: Looking for a X-axis DC servo from older CHNC retrofit

Would the current 16 in-lb motor be a better replacement? It is about an inch longer than the 17 in-lb. It is usable but problematic. It would prevent the cross-slide from reaching its normal X+ limit, and the limit/home switch trip points on a CHNC are not easily adjusted. If there is still a good...

Re: Looking for a X-axis DC servo from older CHNC retrofit

Unfortunately, that length may be a deal-breaker for the Hardinge, because the X motor sits between the motor mount (which moves with the cross-slide) and the back of the bed. Increasing the length of the motor limits X+ travel. The old Centroid 17 in-lb motor is probably around 7.2" from flang...

Re: M200 prompts sometimes disappear

Write a program or macro that includes a line like: M200 "Insert tool and press Cycle Start" Run that program with P10 = 32. Then run that same program with P10 = 0. Do you notice the difference? I propose that M200 should display the specified message (and also wait indefinitely for Cycle...

Re: M200 prompts sometimes disappear

Will you be removing the dependency between M200 and the M0 Jogging option?

Re: H100 vfd

COM and AI1 as noted in the lower left of the diagram.
Where COM = "GND".

You do not connect anything to P12 or AI2.

Re: M200 prompts sometimes disappear

No, I think the problem is that CNC12 fails to cancel the M221 timer when a new message is displayed. M200 does not have or need a timer value, because by definition it waits until the operator presses Cycle Start. Unfortunately, M200 is of limited use, because it only performs its primary job (disp...

Re: dp-4 probing

If your M400 is a pre-2010 model (CPU7 or CPU10 based), then the probe fuse is likely in a white plastic in-line fuse holder near the PLC. Those fuse holders are notorious for getting brittle with age and breaking apart.

Re: M200 prompts sometimes disappear

What happens if you replace the M200 with an M225, and a time limit of zero?

Re: M200 prompts sometimes disappear

His test case indicates the problem is with what came before the M200. He evidently used M221 to display a message that was to remain on the screen for three seconds, but then before that timer expired, ran an M200 that put a new message on the screen. Apparently the timer for the M221 message conti...
