Problem- 0-MC Resets to G54

[tlosparky]

I have a 0-MC with software version 0461-D2. In MDI mode, if the reset button is pressed, the work coordinate changes to G54. I have tried changing Par. 394.6 WKZRST, to both 0/1 (original parameter list was 0) but the coordinate still changes to G54, no matter the setting.

What am I missing?

Work around, while in MDI, program your work offset back in.

In my manual it's 388 bit 6 not 394.

[tlosparky]

Isn't 388.6 for the T control?

[tlosparky]

Yeah, but I'm used to the work offset being modal and I kinda' like things to work like they were intended to.

After each tool change you should have a "safe start block" that repeats all the modal conditions. Inch/metric, absolute/incremental, offsets, etc.

LOL...Isn't the way a machine is "supposed" to work the way the machine tool builder built it?

well there's always something annoying that needs a minor adjustment. For example on Mori's (and possibly all Fanucs?) the memory key has to be in the write protect position to run it. Being a programmer I'm constantly altering stuff until its perfect. I prefer to leave the key off so I fixed it with a PMC setting. I don't care how the machine builder thinks its done

@ford - I understand. But, most of these guys don't know the difference between G-code and ZIP code. Having them change parameters is usually setting them up for a train wreck. Now, I enjoy a good train wreck once in a while. So, if that is the point in changing parameters, then let's get to it. Heck, I bet most of them do not even know that the bit numbers of parameters read right to left and start with 0. Maybe parameter changing should be left to people that have, oh say, 6 years of experience and can actually manually edit G-code with successful results? Just saying. ROFLMBO

Meaning that a modal code is supposed to stay modal until it is changed in programming (including MDI) or power is cycled.

I agree with fordav11. I've seen some irrational things done by MTB. Like not identifying that the tool being called is already in the spindle and just does a tool change to exchange the correct spindle tool with whatever happens to be in the next tool pot of the magazine.

I agree with mfgbydesign that each tool should virtually be a stand alone program, but would only have the G20/G21 in the first safety line of the program.

Well structured programs are those that require minimal input from the operator for the machine to operate safely and efficiently, and allows for relatively fool proof tool repeat/restart when required.

Relying on remembering to reinstate the work shift offset via MDI every time a Reset is made is potentially a prang in waiting. Every good programmer I know include the work shift offset in the code for each tool in the program. Even if the work shift were model, this code is too important to be left to chance. They certainly don't rely on the operator keeping the machine safe via MDI. As stated earlier, that task must be remembered every time without exception, and has the added hazard of incorrect inputs.

My issue is with repeated entry of work offset in MDI mode, if I have to press reset. If a parameter is supposed to address this and doesn't, I would kinda' like to figure out why.
