Nice build! Sorry, can't help with the question.

RE: Chamber circulation fan control
@travasky
I too have a chamber heater that needed a fan. I do not consider it safe to run the fan control from the printer controller unless there is some sort of safety that is preferably totally independent of the controller. In my case I opted to turn the fan on whenever the heater is on (turned on by the power to the heater). My heater is a PTC heater so it has a bit of a built in safety.
Another option is to run a second fan that is software controlled that you can run during the entire print to circulate the chamber air. -
RE: 1LC - extruder randomly stopping/reversing - ≤3.5.0-rc1

Alas, that fix did nothing to my hiccup problem -
RE: 1LC - extruder randomly stopping/reversing - ≤3.5.0-rc1
@droftarts
Do I just upgrade the .bin files? What are the .map files for? Do I just upgrade MB6HC.bin and Tool1LC.bin (I only have the 6HC and the 1LC boards) or do I need to upgrade other stuff?With the .bin files uploaded, this is what I see for the version information:
Nothing seems to have changed on the 1LC firmware and only the MB6HC firmware changed. Is it ok to have three different versions of firmware (between the 6HC, 1LC and DWC)?

RE: 1LC - extruder randomly stopping/reversing - ≤3.5.0-rc1
@dc42, could this bug that you just squashed also be causing my huge number of hiccups as well as the bogus Vin min/max numbers?
I noticed that a few of the M122 Bxxx reports posted in this thread also have large number of hiccups (although not as large as the ones I am seeing) as well as the bad voltage readings.
Please advise on what files I should upgrade to implement this fix so I can try out if it maybe fixes my issues. -
RE: many many hiccups (thousands)
The test print used for the following was in vase mode. Print time was about 14 minutes for each run (hence the much smaller number of hiccups)
Object printed in vase mode but nothing changed on retractions
Hiccups 210
VIN voltage: min 22.8, current 24.2, max 24.2Same object printed in vase mode with no retractions and no reset after first layer
hiccups 202
VIN voltage: min 22.8, current 24.2, max 24.2sent M350 E4:4:4:4 I1 to change microstepping on all extruders to 4
same object as previous print, vase mode, no retractions
hiccups 49
VIN voltage: min 22.9, current 24.2, max 24.2The last object did not print as I didn't correct the steps/mm parameter to compensate for the lower microstepping
Since the number of steps have been reduced substantially (divided by 4), the hiccups went down accordingly.

@gloomyandy
OK, same print as before but on B23
M122 for the 6HC - no hiccups, good voltages
b21 - no hiccups, good voltages
b22 - no hiccups, good voltages
b23, the tool board that just finished printing:
hiccups 44029,
VIN voltage: min 0.4, current 24.2, max 39.4
b24 - no hiccups, good voltages -

@T3P3Tony
Thanks, I will give your suggestions a try once the current test print has finished in roughly 6 hrs. -
RE: many many hiccups (thousands)
@gloomyandy
I will run the same print on another tool and will report back -
RE: many many hiccups (thousands)
Latest print,6.5 hours
tool board diagnostic:
hiccups 51778
VIN voltage: min 0.8, current 24.5, max 45.3Diagnostic for the 6HC for the same print:
Supply voltage: min 23.7, current 23.8, max 23.9, under voltage events: 0, over voltage events: 0, power good: yes
hiccups 0
both boards use the same power supplyThe print completed despite the nutty numbers.
This is looking (IMHO) more and more like a firmware or hardware design issue -
RE: sd card almost full .. new printer set up
Ahhh I see you are back in business - excellent!
Keep in mind that all the print files you send to the printer are stored on the card so look at the old 'jobs' files and do some house cleaning on occasion.

RE: sd card almost full .. new printer set up
@Richard-F
If you deleted any .bin files that have 'mini5plus' in the title then you need to replace them from the release files.
What was suggested was to back up all the files, reformat the SD card, set up a single partition (boot) and restore all the files. This will give you another 6 gig of usable drive space.
If it was me, I would leave the original card alone, squirrel it away for a rainy day, get a 32 GB card and format it as a single partion. Re-install all the files and Bob is your uncle .... -

@Phaedrux
Yes, PrusaSlicer has a view for volumetric rate. Depending on what I am printing with, I have set 10 mm3 for PETG and 12 mm3 for PLA. -
Hiccups and the 1LC tool board
I would like to ask a favour:
If you are running a 6HC main board with a 1LC tool board, I would like to find out what your hiccup count is on your tool board after a print has finished.
M122 Bxx will report the details. xx is the CAN address of the tool board that just did the printing.
Please run M122 Bxx at the beginning of the print to clear the hiccup counter (it resets when the command is run) and then run the same command after your print is finished. The print should probably be more than an hour on the tool board in question - no tool boards that do things like support or separation layer that run only very few movements.Thank you in advance!

RE: many many hiccups (thousands)
Another tidbit of information I have discovered - the number of hiccups is directly proportional to the extruder step rate (or number of steps taken during a print).
I decided to try and print with a much lower step rate and a print that had previously generated thousands of hiccups ended up with 105 hiccups. The steps/mm for this extruder should have been 830 but I ran the print at 32 steps/mm.
I don't know what it means but this is the first time I have been able to correlate the hiccups to something.
