Stopping a print takes forever

[StrikeBack83]

Stopping a print at the beginning while heating up nozzle and heatbed takes forever (couple of minutes) or crashes the whole machine!
How to determine why this happen, this can't be normal?

[Manuel@Raise3D]

This is expected whenever a print is either paused or stopped when initially heating as the starting Gcode heat-up commands have already been sent to the printer. The workaround for this would be to power off the printer and power it back on, however, you will see the power loss recovery error come up when powering the printer back on. This would be normal as power was abruptly cut.

I've experienced the same when pressing the red button (set to switch off LED light)...
the printer "waits" to complete the current movement before it runs the command.
This must be completely firmware related and is a real hussle at the beginning when heating up.
Heating the bed to 100°C takes a long time so this is not ideal and i cannot understand this software issue. This is just bad design, and never seen at another printer. I hope this gets improved with a future firmware update!!!

In regards to the sleep button feature, I will go ahead and test this out on my end to see if this can be replicated. Can you confirm what current version of touchscreen firmware you're on? Settings > Machine tab > version (Not firmware version)

As for the bed being slow to heat, the E2 typically reaches 100c in about 10 minutes and is expected for this particular printer. Is your printer taking much longer by chance?

I can report the same issue. The turning on of the LED’s in sleep waits until the current move is done.

You can try this by printing a long straight line like a skinny rectangle. The LED’s won’t wake from sleep until it turns the corner. The screen will come on instantly though.

I’m on the very latest of all firmware’s (touchscreen, main, etc…) since I just checked for updates 3 days ago.

Funny enough, using RaiseCloud to turn on the LED’s takes even longer. 30+ seconds at times. Unrelated to how the movements happen it seems.

Unfortunately, it’s because the bed is clearly running off 24V or 12V here. A lot of beds are running directly off the 110V AC, making them heat up much quicker but the E2 seems to heat via DC.

Let me know if I’m wrong on that assessment, but it definitely seems to be the case with how long it takes. 10 minutes is about what I get on my E2 as well, but it seems much longer than usually expected.

Sleep function LED lights update: Yes, I can confirm that the sleep function has a delay until the hotend movement is complete.

As well, the bed is running off of 24VDC which is why it can take some time to reach the higher bed temperatures.

I will forward these two concerns to our RaiseTouch development team for review and see if there's a firmware update that can address this.

[Manuel@Raise3D]

Small update on this.

Our team has responded back and has let me know that yes, the observed LED light behavior is expected, however, they will try and see how to get this to be more responsive through an update (no word yet on the bed heating concern).

I've tested it now and recorded the time this printer takes to heat up from roomtemp. to 100°C:
Starting from 26°C
10min. to reach 77°C
15min. to reach 89°C
20min. to 98°C
So i have to wait at least 20min. to start a print!
And this is a brand new printer bought in april 23!

Thank you for the feedback on this concern. Can you provide me with the printer's serial log file? That way our team has a documented log they can go off of when looking into this. The serial log file can be obtained by inserting a USB drive into the printer and tapping on settings > More settings > serial port log > "export" selection (select the inserted USB). I can then forward this log to our team for review.

Log attached. I'm very curious whats wrong with my printer

[Manuel@Raise3D]

As previously mentioned, it can take some time (about 10 minutes or so) to reach 100c on the E2, however, it looks like something might be amiss with your particular printer as it looks to be taking 20 minutes to heat. There is also one instance on May 10th, 2023 where the printer displayed the following error: Error: Heating fault on heater 0 (bed), temperature rising much more slowly than the expected -0.0°C/sec.

At the time, the bed was at about 94C/100C so it was not too far off from the target temperature. Since it did not fully reach that 100c value in time, the error was likely triggered due to that. I recommend making a support ticket just to double-check and go a bit further into detail to test out your printer's bed just to see if there is any real issue with the current hardware. A support ticket can be made here: https://help.raise3d.com/support/home

As well, our team has also let me know that a software update cannot address the slow heating bed concern as that is hardware-related and not software related.

[StrikeBack83]

Ticket created... but i already know that the only solution for fixing all this problems my machine has, would take me to send it to okm3d, and i do not want that. Packing this NEW machine and send it on my cost to support is just not tolerable!

[Manuel@Raise3D]

Since you are going through a reseller, you can relay to them that there could be an issue with the bed as it's been taking 20 minutes to get to 100c. If they come to the conclusion that hardware needs to be replaced, I recommend seeing if you can order the part(s) through them (the reseller) and then install them on your end to help with saving both money and time (using our online installation guides).

One thing that I did forget to mention is that you can try changing the heat-up sequence on the Gcode tab and see if that helps with how long it takes to heat up the bed. If the bed and nozzle are set to heat up at the same time, it can take a bit longer than just heating up the bed first and then the hotend. This can be changed by following the image below:

I already made it through "Troubleshooting E2-Heatbed Fails to Heat Up" and the resistance value is not correct. Seems like my heatbed is really faulty. I will get in contact with okm3d to get a replacement.
After i disassembled my current heatbed and reassemble it, it's not flat anymore. I tightened all 5 screws against the springs... is there a guide how to get it leveled?

Never mind, i found the guide: https://www.raise3d.com/academy/how-to- ... on-the-e2/

[Manuel@Raise3D]

Yes, that's the bed leveling guide.
