[Ultimaker 3 - Print start warping 4 hours into print]

Hi Nicolai.

Warp deformation is happening because different parts ot the printing piece have different temperatures.

You mentioned that you opened the door and let the cool air in to the chamber... This can cause warping 99% of the times..

 

Usually to keep temperature of the part more or less equal we use heated bed.

 

I would try to not open the door at all during the print since melting point of the whole part will never be achieved inside...

 

Happy printing!

 

[Cura3.3 cannot connect printer via USB]

Cura3.3 cannot connect printer via USB.

But Simplify3D can connect to the printer.

Is it the bug of Cura3.3?

Here is the log info.

Thanks!

 

Hey there.

According to your log file, you are having "Permission Error".

Are you connecting with S3D *AND* Cura at the same time?

Basically, a first application which opens usb port for writing will win:)

 

[Ultimaker Board used for cnc mill]

Hi there. Its possible however you want to understand what you are doing.

First you want to make sure you have right stepper drivers for your motors. For example if this is turning mill with nema 17 type motors you are fine. If you are planning on controlling cnc router with nema23 you may need to replace onboard drivers with more powerful ones.

Next step will be uploading new firmware to your board. Marlin can control cbc mills or you can just upload grbl firmware. All will depends on your application.

Basically treat your board as ramps1.4 board with Arduino compatible hardware.

 

The board will not work off the shelf and will require time investment from you.

Are you printing via USB wire?

[Ultimaker 3 style autoleveling on an Ultimaker 2]

Hi everyone.

I am working on the subj for my UM Original as well.

My thought was to hide "capacitance logic" from Marlin FW. For Marlin, this module is a simple Z Min switch which is either 1 or 0.

[Igus Drylin bushes?]

The outside diameter of IGUS bushings is 16mm so you have about 3mm before you hit 12mm Z rods. At least this is how it's on UM2go I am building... jfyi.

I am still trying to fit IGUS in another build. I'll keep posting when there is a progress.
