Hi,
I wrecked my hot end this week. I think it is due to a design flaw in my hot end. Most hot ends are cooled. There is a fan on the hot end that prevents the heat for reaching to far up the supply line of the filament. Something like this
My hot end doesn't have any cooling. The PTFE (is it PTFE?) tube goes directly into the hot end. There are really small cooling fins attached to it with no

Thanks for your response Roxy.
Your right. I have a Graphical LCD Panel on the machine.
I modified the firmware by editing the two values. This was a big improvement. However, the stuttering occasionally still occurred.
I had to set the LCD_UPDATE_INTERVAL to 1500. That seemed to be high enough. The printer is now working perfectly. I didn't try 1000.
This large value does decreases the usef

I have a strange issue with my printer. The printer head stutters when executing difficult moves.
Here is a movie
A difficult move is a fast curved motion or a lot of very fast short movements. It almost seems that the processor cannot keep up and therefore stops the printing head for a short period of time.
The printer is rather obscure printer (ProDesk3D). It currently runs on Marlin 1.1.

Thank you for your response. I added idle(); to the loop and it works!
I agree that editing de G29 in such a way is a ugly way of doing things. I decided to try it this way because I don't think there is any function in Marlin that supports this strange way of calibrating the table. There is no probe involved in this procedure. The head presses down on the table. The amount of mm that the head is

That could be the case.
I personally think it has something to do with the way I programmed the movement of the disc. The printer sends a busy response through the serial connection while executing a XYZ movement (G1). So normally the printer is running multiple processes at the same time. My code seems to prevent multiple processes. There is no response through the serial. I think the program i

Hi to you all,
I have a problem with my 3D printer. The original firmware was really bad. So I set out to write my own firmware. The printer is a rather obscure one with what I think is a one of a kind table calibration method.
Here is a video of the original firmware at work.
I'm trying to write a custom G29 command in Marlin_main.cpp. This is way above my head. I'm a absolute beginner.
