Upgrade Creality Ender3V2 Firmware and add BLTouch
Posted: Wed Apr 06, 2022 1:35 am
Some of you may have followed my trails and tribulation with my trying to get my Creality Ender3V2 working correctly https://gardenrails.org/viewtopic.php?f=56&t=13661
After giving up a while ago due to some health issues I finally bit the bullet and bought a BLTouch kit to add to my printer.
I followed this YouTube video to install the probe and cabling https://www.youtube.com/watch?v=TroPjdkSEOY as the instructions that came with the kit had print that was near on unreadable as it was so small.
A bit more searching of the net turned up this firmware upgrade that I installed https://www.youtube.com/watch?v=o1zXYwgIPLY as well as this instruction guide from Smith3D (a Malaysian based organisation that kept turning up in my searches and had some good reviews) https://www.smith3d.com/ender-3-v2-blto ... ith3d-com/
The Smith 3D page led me to this page where the firmware upgrade was available https://github.com/Jyers/Marlin/releases/tag/v1.3.5.b
I have a V4.2.2 board in my printer so I downloaded the E3V2-BLTouch-3x3-v4.2.7-v1.3.5.b.bin file this gives me a 9 point scan of the bed by the BLtouch (choosing the 5x5 would give a 25 point scan) there was also a HS option which is "High Speed" that does not retract the probe between points.
I added G29 instead of M420 S1 into my Creality Slicer Start G Code as I wanted some confidence that my bed is still level at the start of each print, it does add a bit of time to the print but I can live with that if the end result is a good print.
The probe X,YOffsets came preset at the levels in the firmware download so all I had to do was confirm the measurements.
When setting the Z Offset I heated the bed and nozzle using the "Preheat PLA" function.
Additionally I add stiffer springs to my levelling knobs because the stock ones did not seem to hold the level adjustment.
One trap for young players is that I installed the probe bracket upside down and when it tried to probe the bed the nozzle crashed into the the bed and kept trying to drive lower.
Overall I am happy with the BLTouch install and look forward to printing some projects once I master Tinkercad
Hopefully this may help somebody new to 3 D printing from falling into the same traps as I did.
I did also look at Octoprint (I have a Raspberry Pi 3B sitting idle in the shed) but that is something for the future.
