With my standard V1.0.2 software, I was able to override the factory 1000mm/min XY speed settings using Simplify3D and override scripts, to achieve 80-100mm/sec on 3D benchy with good print quality. As a result, I know the machine can go faster, but for whatever reason, no matter how fast I program it on Simplify 3D, it seems there is a hard limiter on the printer firmware preventing it from exceeding the 80-100mm/sec I have achieved (aka increasing the speed in the Simplify 3D and the script overrides doesn’t lead to a faster print anymore).
So today I upgraded my software to V1.0.7 from the Creality website; however the max XY speed values on the machine changed from 1000mm/min to only 600mm/min. The goal was faster, not slower…
I have the V4.2.2 motherboard running a STM microcontroller. I have a direct-drive extruder. Can someone please recommend to me a different firmware update I can use to boost my speeds? I believe I can go up to 120mm/sec reliably with this printer, possibly even 150mm/sec if I upgrade to a linear rail system, but I’m currently being limited by the firmware. Thanks in advance for your suggestions
I’m not a programmer by any means. I can work within the confines of Simplify 3D to customize a print, but programming something like Klipper and running a secondary raspberry pi or other device along side the computer seems like it would open me up to more issues than anything else. Do you know of any detailed guides for doing what you suggested? The Klipper website looks like it was built in the 80s… I haven’t found much that is visually helpful.
It’s surprisingly simple, especially with a raspberry pi, there are hundreds of youtube videos breaking it down step by step, often for a specific printer too.
I think it took me about 10 minutes the first time on my old ender 3 (2021 edition) which also ran on the 4.2.2 board.
I think I followed this video the first time, it was a while back, this one’s got a section specific to the Creality 4.2.2 board.
If you want to skip to the important part, flashing the firmware on the 32bit 4.2.2.0 board:
(This is essentially the hardest part of the process, so if you can get this everything else should be simple)
Don’t expect to know everything right away, I’ve been using Klipper extensively for about a year and I’m still finding new tricks and techniques. There’s always something new to learn.
