EC 2.3: HBP never turns off? about g3firmware HOT 9 CLOSED

Hi,

The HBP output is also shared, in the default configuration, with the valve output. If the valve is turned on or off, the extruder controller will assume a valve is hooked up to that output rather than the heated build platform.

Can you scan your g code for M126/M127 codes? These are the ones that turn the valve on or off.

Going forward, I'll add code to replicatorG to ensure it doesn't send valve open/close commands if they're not configured in the machine descriptors.

If on the other hand you don't see any M126/127 codes in your generated gcode, please add a comment to this bug so I can look for other causes.

I don't have M126 or M127 in any of my gcode files, I just scanned a bunch of them. I also didn't touch any settings regarding a valve in RepG0015.

Hm. Can you mail me the gcode file at [email protected] so I can take a look and see if I can reproduce the problem?

I've seen this behavior as well. The HBP control worked fine using the control panel but didn't turn off after a build. Also, the HBP temperature was over 120C at the end of the build, instead of the 100C specified in the gcode. It's possible there's a stray M126 or 127 in my gcode. I'll check that tonight.

No stray 126 or 127 codes. To reproduce the problem, I loaded MB v2.1 and EC v2.3. I took a gcode file and started removing lines to narrow down the source of the problem. I ended up with two lines:
M109 S100.0
M109 S0.0

adam -- I think charles pax found this problem in replicator? he was talking about submitting a patch.

I'll check in with him; thanks,

The bug was in ReplicatorG; fixed in 0017 (if not earlier).

I can confirm: new firmware on the EC (2.3) and now the HBP cycles correctly. Thanks!
