[UM2 - printing via USB]

Thanks! That did the trick.

One last question: is there a way to keep the printer printing while removing the USB cable? 

[UM2 - printing via USB]

Dear all,

The laptop I am currently using to draw models and export printing files from Cura (version 4.3.0) does not allow communication with SD cards without BitLocker encryption. Therefore, my UM2 can't read the card.

The only option that is left is to print via USB, which gives the following issue:

 When clicking "Print via USB", the head immediately starts to traveling (along a path that appears to be the correct contour of the product I am trying to print) , but without heating the bed and the nozzle, without raising the bed into the correct position and without extruding (feeder is not activated either). 

 

What is going wrong here? 

Thanks in advance!

Miron

I solved the issue eventually by having a reseller upgrade the machine to 2+.

IS there anyone who can advice a service location close to my hometown Enschede (The Netherlands) where I can bring the machine and have it diagnosed/fixed?

So there are about 10 things that come to mind that cause this so it would be nice to get more information.

 

1) One possibility is that the 24V is not reaching the servos and heaters.  This is common.  Do the servos move at all?

 

This is easy to fix and would explain why both heaters have issues.

 

2) If the servos move and if it reads correct temp but does not warm up then your heater is defective in some way.  It could be as simple as the cable isn't quite inserted at the PCB - it corrodes or can come loose so remove and reinsert the heater wires. 

 

3) If it still doesn't heat up then remove the wires again and check the resistance with a multimeter.  A working heater is around 20 to 30 ohms.  A broken one is usually infinite ohms.  But check these wires while not connected to the PCB.  If it's infinite you need to buy a new one.

 

If you don't own a multimeter hopefully you have a friend who does and knows how to use it.  Everyone should have such a friend.

 

Dear gr5,

Thanks for your response!

The servos work normally. 
I measure about 30 ohms of resistance when disconnected from the PCB (wires don't seem corroded whatsoever. 

Any other suggestions?

Best regards,
Miron

Hi Miron,

 

if you manually set a temperature for the nozzle, does it heat up at all?

At which time and at which target/actual temperature does the error appear?

 

 

When I manually elevate nozzle temperature, I stays  at ambient temperature.

When I manually elevate  the build plate temperature, error message ER03 occurs.

Hi all,

I have recently bought a second hand UM2. The very first time after the seller demonstrated me the working printer (but after transport), it gave a heaer error. 

A followed the tips on the troubleshooting page of Ultimaker:
- The firmware was updated via Cura
- The nozzle and temp sensor were checked for full insertion
- The nozzle is nicely centered and does not make contact with the bracket

- Then I  replaced the heater block (which looked quite worn out) but still the same error.

The last tip UM provides is that the heater cartridge is not strong enough. Does anyone have experience with this issue?

Thanks in advance!
Miron
