Hey Y'all, I have a Cr-10 Mini with an upgraded mainboard. I know this is a group for ender 3's but I beleive someone here could help.Everything was working well and one day my BL touch stopped working and is crashing into the bed. I dont beleive this is a coding problem, but Im stumped and dont know what to do. It would be appreciated if someone could provide some idea on what to do. For context, I have a Cr-10 Mini with a BTT SKR 1.3 Mainboard, and a Bl touch.

I have a design which uses two filaments, TPU and PLA and have found the TPU does not adhere well to the PLA base instead it pills.
Is there a rigid filament for the base other than PLA that may work better, possibly ABS, PETG? The TPU is perfect for my use and I'd prefer to not swap that out. FYI, I use the post process "pause" command, which works well to notify me(beep), to reposition the extruder and to extrude the base filament in preparation for the next filament. The nozzle stays hot during the process allowing me to advance the next filament easily without much loss of either.

I’ve got a ender 3 v2, I’m just a real beginner and I used it before for some prints and stopped using it , now I’m going to use it again, I calibrated everything including Z offset as I have a bl touch and I tried printing the cube , everything looks good including the measurements but one edge is not straight and smooth and rest is ok so need some help with it

I'm a relative newbie to this game and am experiencing an issue wherein my print is furry in some areas. I've tried altering nozzle temp but no joy. I do not understand very much about gcode etc and use it only when bed levelling with a bltouch. My machines has twin screws on the axis and a BLTouch otherwise it's pretty standard. Hopefully the video will demo what the problem is and someody will be able to help me prevent it in future prints.

Anyone have expertise in getting an Ender 3 connected via micro USB since I have the 32Bit 4.2.2 Board - When I connect a cable to it and to the PC, nothing happens

Hi people,
On my second ender 3. The glass bed supplied with printer, seems as though it’s becoming quite marked, never had this on my other Enders glass bed
Any ideas most welcome

Thought I would share this:

Marlin 2.x for 4.2.2 - Autobuilder

And I made this...
Marlin 2.x for 4.2.7 - Autobuilder

TRYING TO ADD FILAMENT SENSOR

I have an ENDER 3 with an upgraded V4.2.7 mother board, and a CR Touch. Everything works fine.

I am attempting to add a filament runout. When I upgrade the firmware for filament the nozzle heat errors out with E1. Example, I set temp to 260C, the heat runs up quickly and steadily until approximately 250C, then stops and stays at 250C until the error occurs and the printer is stopped. This happens at all temperatures, the heating stops ~ 10C below the requested temp, and stays there until errror.

I have tried 3 different runout sensors and their cables, and 3 different motherboards. This occurs whether or not the sensor is connected, whether or not the sensor is turned on on the screen.

When I flash a firmware that does not include runout, everything is fine.

I have spent quite a bit of time with emails to Creality support, they have been unable to help.

I think this has to be firmware.

I can't be the only Ender3 that has installed filament runout. Has anybody had this problem with maybe a solution?

Thank you for any help,

Mike

Hi everyone, I was wondering if there is a company in the UK that recycles filament scraps to make new filament. I don't want to buy one of the machines and I don't think I could make my own. Thanks in advance.
