IDEX Homing Issues
-
I have a IDEX printer with the leveling probe on the X axis. I have a G28 in the start script to home all before the program starts. When I start a program that uses the X axis tool with the printer not yet homed it homes fine and starts the program. When I try this with the U axis tool it homes X, U, and Y but then stops before leveling the bed and sits idle. The other thing is if I home all before starting a program that uses the U axis tool it homes and starts fine.
Does anyone know why I would have to home all before I can started a program with a home all in it, only for the U axis tool?

We'd need to see your files to have much of a guess.

Ok, I will work on cleaning up my config a little so I can post it but if it was not clear in the description, the problem is that T0 is active with the start of the program and set to a temperature, then after the y-axis is homed, it switches to T1 which has the probe to do the z homing but T1 is at room temperature so the firmware wont allow it to do the probing because its not at temperature. I tested this by heating both extruders with the start of the program and it homed and started fine.
Seems to me that the firmware does not realize that the tool probe does not need to at temperature to do the probing.

@Phaedrux I solved the issue by taking the "wait to temps stabilize" out of my slicer and instead put it into Tpre0.g by adding a M116 P0.

@Phaedrux
That caused another issue... Since I'm using Tpreo.g now it also runs Tpost0.g at the beginning. Which is actually good, I wanted to do a purge first before it starts so that will work. The issue is when the program first starts it purges at X80, but when it does a tool change it purges at X98. This is because T0 starts at X-18, off the bed. I'll have to find a way around this so the first and sequential purges are at the same spot.It also says "attempting to purge without a tool selected" and I think that's because T0 is currently in standby and not active, but that is what is allowing it to home z. I think I need to tell it that T0 is active in TPRE0.g.
-
Found out what was causing the purge location issue was because when I cleaned up the config I put the M208 before the M584 which messed things up. I moved it back down and it solved that issue. Now just have to find a solution for the "attempting to purge without a tool selected" issue.

@Phaedrux The other strange thing is if I manually home, and then start a program using tool 2 (copy) it only turns on tool 2 (H1+H2) and starts just fine. If I do the same thing but with a G28 in the start script. It turns the heater for tool 0(H1), and tool 2 (H1+H2) and (not tool 1(H2). Why would calling for home change which heater is turned on? Why is tool 0 being told to be active. There are no T0's in the program, homing, or macros.
-
What do you have in your tool change macros? Tpre, tpost, etc?
-
@Phaedrux Nothing now, I commented them all out to see if that had something to do with it. It didn't change the result.
-
What's in your start gcode?
Can you post the first 50 lines or so of gcode from the sliced file?
Tool changing isn't my specialty, so I'm not really sure what could be going on.
-
It starts fine as is, if I remove the semicolon in front of the G28 that's what causes the issues I described previously with T0 and T2, T1 is fine with the G28 in place.

@Phaedrux Looks like a T1 in the home all fixes it. I dont understand why you have to call the tool probe as the WIKI states that the probe must be on the X axis tool.
