You are doing it wrong… I know

Hello Ian.
Did the PID tuning and then M500 to store them. I've also updated those values in the config.g just in case. Checked config-override.g and the values are indeed being updated.After the tune, heater is working good though. It heats and maintains that temperature very steady.
The issue is just the extruder motor.Steps/mm are the same as when it was a 12v system. I was using the same 0.9º motor. Or does the step/mm change when using a 24v PSU?

Which extruder are you using?

Hi pogo, it's a Titan Aero.

…...................
Steps/mm are the same as when it was a 12v system. I was using the same 0.9º motor. Or does the step/mm change when using a 24v PSU?No micro stepping doesn't change. As you made specific reference to the extruder motor, I was just wondering if you had changed the motor at the same time as changing to 24V. Clearly not the case then.
Your description of what is happening is consistent with a restriction preventing the filament from coming out of the nozzle as it should. I can't think of any reason why changing to 24V would cause that so am inclined to think that it must be co-incidental. If the hot end is getting up to temperature, then it would indicate a blockage or partial blockage.
-
Hello Ian, I can confidently assure that the hotend is not blocked. After swapping all the 12v items for 24v ones the heater block received a full clean service
Either way, I was trying to extrude with no filament loaded. That's why I'm perplexed by this issue.As soon as I get home I will try by playing with motor current and idle factor.
Don't know what else to do. -
Sorry. I'm struggling to understand what the problem is. In your OP, you said this:
"The problem is that the extruder clicks when trying to extrude".
I assumed from that you meant that you were extruding filament.
So, are you saying that with no filament loaded, when you use DWC to extrude, you get this clicking noise? Do you get the same behaviour with filament loaded? Does the extruder gear rotate? Have you checked that the grub screw holding the gear on the motor shaft is tight? What happens if you take the motor off of the extruder - does the motor itself rotate as expected?
Just trying to pin down what the issue is.
-
What speed are you trying to extrude?
Am I correct in understanding that the extruder drive and motor were the same between 12V and 24V setups? Did you change the wiring at all? Are you sure you commanded an extruder speed that worked with 12V in the past? Can you try a slower speed? 5mm/s is plenty to at least test that it’s wired properly and configured in a usable enough way for further testing. Can you double check that the motor connectors are fully seated on both ends of the wire? If it’s seated correctly, is there any chance the motor wire got damaged during the upgrade?
A full amp should be OK for that motor, unless you know from experience with that motor that the motor will get too hot.

Sorry. I'm struggling to understand what the problem is. In your OP, you said this:
"The problem is that the extruder clicks when trying to extrude".

Yes, sorry, I struggle with the English language sometimes.
Hard to express myself properly.So, are you saying that with no filament loaded, when you use DWC to extrude, you get this clicking noise? Do you get the same behaviour with filament loaded? Does the extruder gear rotate?
Yes indeed. I've tried to extrude with no filament loaded and with filament loaded. In both cases the extruder gear won't rotate.
Have you checked that the grub screw holding the gear on the motor shaft is tight?
Yes, the grub screw is tight.
What happens if you take the motor off of the extruder - does the motor itself rotate as expected?
Did that, the motor shaft won't rotate in this situation either.
To sum up, I can make the extruder motor shaft rotate with 12v but not with 24v.
-
What speed are you trying to extrude?
The lowest possible when using the DWC.
Am I correct in understanding that the extruder drive and motor were the same between 12V and 24V setups?
Yes, it's the same.
Did you change the wiring at all? Are you sure you commanded an extruder speed that worked with 12V in the past?
The wiring is the same. Yes, I'm sure, double checked that.
Can you try a slower speed? 5mm/s is plenty to at least test that it’s wired properly and configured in a usable enough way for further testing.
I don't think I can, I was trying with the lowest speed available in the DWC.
Can you double check that the motor connectors are fully seated on both ends of the wire? If it’s seated correctly, is there any chance the motor wire got damaged during the upgrade?
Did that, but will do it again as soon as I get home. Maybe do a continuity test too.
That's the weird thing. If fed 24v, it doesn't work, but if I switch to 12v it does. So the motor is ok, and presumably the wiring too.A full amp should be OK for that motor, unless you know from experience with that motor that the motor will get too hot.
Thanks, will try 1 amp too. I remember lowering the amps because of the motor getting hot, but can't recall how many amps were fed before tunning.

….....................
To sum up, I can make the extruder motor shaft rotate with 12v but not with 24v.That sums up the problem beautifully. What we now need is for David (DC42) to comment. I have no idea why that motor works with 12V but doesn't with 24V but David might be able to shed some light on it.

Is the extruder driver getting hot, especially when using 24V power? Does M122 report that it is over-temperature?
-

This would be the proper way to do what you suggested?
1. Connect the 24v PSU.
2. Power up the printer.
3. Set bed and hotend to print temperatures?
4. Wait lets say 10 min?
5. Send M122
6. Report back here with the results.EDIT: typo
-
Add step 3a: command some extrusion, to enable the driver.
-
Well, It must have been a wiring issue (or something else), because now the extruder is working under 24v.
For now, I will rewire the entire extruder connection and see how it goes. If the problem appears again I will report back.Did my homework though, here is the M122 report:
[c]With 24v PSU
Bed set to 60ºc
Hotend set to 180ºc
Hit "Extrude" from DWC. 50mm feed amount, 1mm/sec feedrate
Waited 10 min
Hit "Extrude" again, just in case the 10 min wait could let the driver cooldown.[/c]=== Diagnostics === Used output buffers: 3 of 32 (10 max) === Platform === RepRapFirmware for Duet WiFi version 1.20beta6 running on Duet WiFi 1.0 Board ID: 08DDM-9FAM2-LW4SD-6JKFD-3S46T-93XZX Static ram used: 15472 Dynamic ram used: 97048 Recycled dynamic ram: 2168 Stack ram used: 1368 current, 4920 maximum Never used ram: 11464 Last reset 00:04:24 ago, cause: power up Last software reset reason: User, spinning module GCodes, available RAM 11340 bytes (slot 1) Software reset code 0x0003, HFSR 0x00000000, CFSR 0x00000000, ICSR 0x00400000, BFAR 0xe000ed38, SP 0xffffffff Error status: 0 Free file entries: 10 SD card 0 detected, interface speed: 20.0MBytes/sec SD card longest block write time: 0.0ms MCU temperature: min 21.3, current 29.3, max 29.5 Supply voltage: min 23.8, current 24.0, max 24.2, under voltage events: 0, over voltage events: 0 Driver 0: standstill Driver 1: standstill Driver 2: standstill Driver 3: standstill Driver 4: standstill Date/time: 2017-12-16 16:28:52 Cache data hit count 1113211460 Slowest main loop (seconds): 0.004874; fastest: 0.000041 === Move === MaxReps: 1, StepErrors: 0, FreeDm: 240, MinFreeDm 239, MaxWait: 2677025694ms, Underruns: 0, 0 Scheduled moves: 5, completed moves: 5 Bed compensation in use: none Bed probe heights: 0.000 0.000 0.000 0.000 0.000 === Heat === Bed heater = 0, chamber heater = -1 Heater 0 is on, I-accum = 0.0 Heater 1 is on, I-accum = 0.2 === GCodes === Segments left: 0 Stack records: 2 allocated, 0 in use Movement lock held by null http is idle in state(s) 0 telnet is idle in state(s) 0 file is idle in state(s) 0 serial is idle in state(s) 0 aux is idle in state(s) 0 daemon is idle in state(s) 0 queue is idle in state(s) 0 autopause is idle in state(s) 0 Code queue is empty.
