Simplify3D User Forum

I have been using Simplify3D for about a year and I am starting to experience some unusual moves. I do not know where to start troubleshooting , but thought I would ask here. I have not actually witnessed the problem moves but see the result.

The printer goes home on one or both axis occasionally and returns and starts printing where it left off. I see the witness on the table of the nozzle weeping across the table in the same place in different layers.

I did not get a chance to look at the G code yet. Is there a chance that it is timing out and going home to zero out?

The printer is from an extinct company called Ideator12, pretty standard. I do not think I had the problem before the recent upgraded version.

I did have to re-select the machine when I updated versions. I may have a random G code telling one axis to zero or.... Any idea what G code it would be?

Any ideas on where to look would be good.

Thanks, Ken

The homing command is G28, although, I doubt you're going to see those anywhere except your starting script.

Joe,

Thanks for an idea on where to look.

I will scan for any stray G28's in the program. I believe that there would be an axis call after it? Something like G28 X0?

I will also check the indimension3 Ideator12 profile that I loaded at about the same time to see if the default G code puts anything in it. In the CNC world I would call it a post processor.

It is one of those problems that is not fatal, so it is less urgent to correct and more difficult to find because up until now, the evidence has been the extruder leak across the plate.

The printer is reliable enough that the days of staring at every move are over. I check it about every 1/2 hour now.
