Good afternoon all, I have a CR10S that I upgraded the hotend to a microswiss NG direct drive system. In the test print phase and all prints are under exdruding, where I set the Esteps to 400 from the factory 93 it reverts back with no way to save. I have found out this was a brief period where Creality locked changing these features for my own protection… so my printer likes to print very squishy prints now. I have talked to some knowledgeable staff about upgrading the firmware to Insanity Automations tiny machines, however I am at a loss where to start this journey, a bit over my head. Can anyone point me to a how to for the CR10S? I find a lot of info for a CR10S Pro, but hoping to get my machine running again. Appreicate any help that can be offered ---

The CR-10S has an 8-bit CPU. Because of that, you have to hook it to a PC using a USB cable and software to upload the “.HEX” file to the printer, such as Prusa slicer (Configurations → Flash firmware). You will find insanity automation firmware here: [Firmware Projects – Insanity Automation, LLC](https://insanityautomation.com/index.php/firmware-projects/#) (look for CR10\_DW7.4.7.hex.zip). You have to unpack it before flashing it to the printer. Here is another good tutorial for the TH3D firmware: [https://www.youtube.com/watch?v=17BmvUSKntE](https://www.youtube.com/watch?v=17BmvUSKntE). Hope it helps you. ---

> [@Tiago](#): > > CR10\_DW7.4.7.hex.zip Ok, I got the file and used pursa to flash the machine, everything seems to have gone smooth. In the tutorial using the different firmware, he uses adriuino to edit and control the file.

Thank you. However, my printer just has a lit up blue screen now, I don’t have any menu options at all, is there something I am missing about where the control now comes from? ---

Hey Brian, in order to fix the firmware issue, we used Prusa Slicer and uploaded the .hex file to the printer. How is the printer after that? ---

Has been running pretty well, I have noticed at times I am getting a skip, I think on X axis, intermitent so I am not sure the cause ---

Is it causing layer shifting?
