SKR Mini e3 v3 Marlin Firmware Update

[@jeffreymaes1939]

Bought the board together with the TFT35 screen to upgrade my Anet AM8 and was struggling a little bit. After watching this video everything was super clear thanks to your small tips and 'common mistake' interludes (these helped a lot). I will do the firmware update as soon as possible! thanks a lot!

Hi, about to replace my MKS Gen L on my Ender 5 (original) with an SKR Mini E3 V3. Currently I have the original Ender 5 screen, a 3.5" touch screen at the same time, Hemera direct drive that I am upgrading to a Revo at the same time as all this. Is there anything specific I need to keep in mind when setting up my firmware?

Thank you so much for such a complete walk through of how to do this. You have no clue on how many videos that I watched that just say download the marlin firmware you want and install it into your 3d printer and thats it. And that drove me so crazy. You have no clue how many times I went and download the marlin fw and un zipped it and put it on my SD card and tried to run it and nothing happened. So I really appreciate it so much.

I saw your video on this board install. In it you mention needing a JST connection for the hot end fan. I did not have one and had to order a giant pack to get some (still waiting for arrival). I just saw another person's Y-tube post and he mentioned that since these wires were previously just continuous power, you could put them under the board power wire screw terminals. This gets you going until you can get a JST connector in hand. I thought it was a good idea, it has worked so far.

[@3DPrintscape]

Hi. That should work as well. The only down side would be depending on the board/firmeware, you may lose some control but it shouldnt impact much.

[@armani007E55]

What are the main difference between Z homing and BL - Touch? tks

[@3DPrintscape]

Hi. Z homing is just setting the z position to zero (or a known location). If you dont have a bltouch the printer will use the z stop for it. If you do, it will use that. Its also worth mentioning that with it the firmware will home to 10mm on the z axis. You will need to set your z offset but that doesnt actually come into play until you print something.

[@markkranc4478]

Thanks as usual for the very thorough and informative instructional video. Question unrelated to the E3 V3. I have an E3 V2 which works great, but I'm having difficulty determining the source of a problem with the stepper motors grinding shortly at the extreme (most currently) of my X axis only while performing the bed leveling ( I don't print to the extremes of the print bed so this is likely why I only experience this with the bed probing). This was happening on the Y axis but has changed to the X axis now after I updated my Marlin to the latest Bugfix 2.1x. I have an ender 3 pro heavily modified with a creality sprite pro extruder and a BTT SKR mini e3 v2. No problems with printing or overall operation, only the short grinding of the X stepper when the bed moves to the right front corner. I do notice that the extruder is probing extremely close to the front edge of the build plate all along the X0 Y0 through the X235 Y0 edge. I have the default X_BED_SIZE and Y_BED_SIZE at 235, even though this is the extreme of the build platform and not realistic for the printable area. Any thoughts or suggestions on resolving the grinding issue is greatly appreciated. ADDENDUM: I neglected to add that I'm using a CRTOUCH

[@3DPrintscape]

Hi. Have you tried to clear the eeprom at all?

[@markkranc4478]

I have not. Will try that out. Thank you for the suggestion

[@markkranc4478]

Well that didn’t work. I’m considering reducing the bed size from 235 x 235 down to 230 x 230 in the firmware. Not sure if this will do much

[@3DPrintscape]

@@markkranc4478 What margin do you have set for the crtouch? May be worth trying to make that larger.

[@markkranc4478]

I set the margin to 20 mm. I re-did the firmware setup and reduced the bed size from 235 to 230 mm. I’m still getting the X stepper grinding at the extreme front right corner and a little at the back left corner. I double checked my CURA slicer bed settings and they were at 220 x 220. Not sure what other parameters to modify. The belts aren’t slipping, only the stepper motors trying to move beyond the bed edge. The X axis issue arose after switching to the Creality Sprite Pro head. Before that I had converted to direct drive using the stock ender 3 pro hot end and extruder stepper with a Printer Mods mounting plate. The nozzle offsets were significantly different. Of course I made the offset changes in Marlin. I also adjusted the X and Y min and max values in CURA in my machine setup. I didn’t check how the print head positions in relation to the printer bed and the hard rail stops. That thought just occurred to me. Once again, I’m very grateful for your input

[@dylannziko1782]

Hi, great video, I was able to reproduce all the steps correctly but I have 2 issues: the part cooling fan just won't work at all and bi linear bed levelling starts probing off the bed so that doesn't work. I have at my probe offsets in the advance settings by getting a reference point from the nozzle unto the bed and moving each axis until the bl touch was on the reference point and noted the observed offset.

I appreciate the tutorial very much. It helped me understand how builds are created. I have an ender 3 pro with the SKR mini V3 board and the CR touch. The touch is plugged in to the proper port and the Zstop is plugged in to the Z port. Unfortunately, when I Home the extruder it moves to the proper point and then begins to move down and does not stop, grinding the motor. I did the build twice thinking I made a mistake but same issue. I went to my previous build using bug fix 2.0.x with the SKR Mini Z homing build and it homes accurately on all axis. What could I be missing on the Z? My build was with the latest bugfix 2.1.

I think I have finished all the programming now and the only issue I'm having is a lack of motor current, steps per MM, and stealth chop settings not being set on Marlin. I can easily add them after I upload the firmware.bin file to the motherboard, but I was wondering if I could do it in the configuration files before I create the firmware? I started with the ender 3 pro config files.

Hi there, thank you for the very informative video. I'm a complete noob when it comes to the firmware, but sooo keen to lean. I have added a Bigtreetech Microprobe V2, on the SKR mini e3 V3, on my Ender 3 Pro. I followed all your seps, excluding-the Bltouch and defined the Microprobe. The Auto level fails, from old corner home position, the extruder moves to the center about 4mm above the bed, raises by 10mm, probe is deployed but comes shy of touching the bed and fails. I have lowered it to the lowest point but still fails. Could you maybe point me in the right direction for it to lower till it probes the bed?

[@3DPrintscape]

Hi. Is the z stop being triggered or is the nozzle hitting the bed at all?

[@sebastienchiniah5720]

@3DPrintscape thanks for the reply. The probe doesn't trigger at all as it doesn't touch the bed. And the printer screen says failed please restart.

[@3DPrintscape]

@@sebastienchiniah5720 Does the probe deploy like its supposed to and if so can you trigger it manually with your finger to see if it stops.

[@sebastienchiniah5720]

​@3DPrintscape hi, I'd does I've changed the z safe homing hight from 10 to 8. It goes through the leveling. After homing again it fails to go low enough to trigger. I manually move all the axises to 0 and did it again. But it just can't seem torecognize that the bed leveling is lower when homing.

Hello, One thing i'm not clear on is having the z-stop plugged in while using a CR-Touch? Do you have something that discusses this further? I have an Ender 3 V2 with the SKR Mini E3V3, TFT35, and a BIQU H2 Revo extruder/hotend. Please help!!

@@nomadu571 Is it pulling on the wires or anything? Ive seen that happen when there was a loose wire/connection.

I've checked the wires and moved them out to the front of the machine so I could check them and see, also make it easier to check connections etc and I can't find anything wrong with the connections. It was working fine before I changed mainboards, my other board, the part cooling fan pins died, so I had to change. The only thing I can think of is that it's an older 3rd party one I inherited with the machine, which ran off the 3v servo pins on the last board, so maybe it can't handle 5v? I was debating buying a new one when I saw a lot of posts regarding the e3v3 board and bl/cr touch issues. People experiencing the same things as me.

I am trying to compile Marlin firmware bugfix 2.1.x for my ender 3 Pro with SKR MINI E3 V2 and CR Touch. I followed your video accurately. I think I have everything setup properly and it compiles correctly. Everything is working except for the Probe Offset Wizard. It goes through the normal routine (homes, etc), but when it gets to the step where it would normally lower the probe so you can adjust the probe z-offset, it just seems to freeze and nothing happens and I have to power cycle to get it to work again. Also, I don't see the normal "0.2 mm Shim" on the LCD, like it used to show at this step. However, I can use the "Home Offset Wizard" which does show the 0.2 mm shim. Has something changed on how this works from bugfix 2.0.x to 2.1.x? What is the purpose of the Home Offset Wizard vs the Probe Offset Wizard? Which should I be using? Can someone look at my config files and let me know if something is incorrect? Any advice is appreciated.
