I’m looking to understand why my printer has decided to malfunction.
I’ve had the printer for about 9 months, and after some hair-pulling and resilience, managed to get it working fantastically for the past 6 months…until now.
Whenever I send a print to start, the motors appear to begin to slow down as if not enough current is being supplied. When the motors are activated individually (manual movements) they work fine, however it is only when they need to work simultaneously does the problem appear.
Any advice on what to test/try would be greatly appreciated. I can supply more information where necessary.
I believe it could be a power supply issue but would love to hear your suggestions, [color=#0000FF]these forums have certainly served me well in the past[/color]!

Sounds like a power issue or bad stepper driver.
Can you post a video of it?

[quote=“Paul Compton”]Stepper motor either step, or not. Their speed is not dependent on supply voltage.
Somewhere in your software, there will be a step/feed rate for manual control.
Likewise, there are step/feed rates for different printing moves.[/quote]
Thank you both for the response, I will upload a video this evening when I get back to the printer.
The movement (x, y, z) is fine individually and can also be ‘homed’ without problem
The extruder will heat up to temperature and extruded as normal
The bed will heat up to temperature as normal
HOWEVER when more than two of the functions above are activated, the printer seems to cut out like the stop button has been activated and I notice a sudden drop in extruder temperature.
0s-18s: Heated bed on and movement activated - works fine
18s-39s: Extruder on and movement activated - works fine
50s-1m04s: Heated bed and extruder both activated - manages to home but sudden drop in 20degrees occurs AND extruder and heated bed automatically de-activated
1m04-1m27: Extruder begins to re-heat again after manually re-activating
For your interest, the part seen on the bed (12s) is a heat-activated filament (goes yellow when warmed). I FINALLY found a use for this property - showing you guys the bed is hot ha!
When the problem occurs, the log reads the following:
Brown out Reset means a power issue (power loss). Your printer is draining too much power for the PSU or there’s a bad connexion/contact between PSU and Printer.
Just as raby said, ther is a serious issue with your power supply.
Can you examine if that reset happens during a specific combination of heater/bed on/off and motor movement?
Maybe check if your screw terminal for 15V is correctly soldered.
Mine wasn’t, causing sporadic brown out resets when the printer vibrated.
Aslo look for (possibly temporary) shorts in the heater/bed/motor wiring.

Hi all,
The reset occurs only when the heater and bed are both on, then attempt for movement.
I’ve ended up trying an alternative power supply which seems to have corrected the problem so i believe it was just the power supply that was faulty. Do you still recommend to check for any shorts, and if so how can this be done?
Do you have advice regarding sourcing replacement parts and whether Veleman are able to supply if i send back the faulty power supply?

Well, if you are sure it is a faulty power supply just get a new one.
If nothing on the PCB (especially stepper drivers and power regulators) heats up unnormally you should be fine then.
The stock power supply is almost at it’s limit when both bed and heater are on.
That, and the fact that only a higher voltage supply allows higher bed temps for ABS made most ABS printing users
fit a second (24v) supply for the heatbed. Then the stock supply will easily power the rest.
Most likely your power supply is still under warranty (2y), so if you return it together with proof of purchase and fault description, we’ll examine it and exchange it if necessary.
