Re: Project "Get my printer printing reliably"

Looking good Jubbp the quality of the prints are getting better and better.

I've been working on my ender over the holidays and its had a few upgrades, still fighting with it to get better quality out of it.

"DJCoopes I've been using cura since I started with my ender, what you stuck on?"

Re: Open source ECU's Highs, lows and blue smoke.

Over the holidays I spent some time learning FreeCAD, I redesigned the face/connector plat for the v4 speeduino to make it more flexible and with a little more space.
Hopefully I'll have it bench testing in the coming days.

Re: Open source ECU's Highs, lows and blue smoke.

Update 12/11/2021
My electrical apprentices and myself were successful in getting opensource STM base Speeduino to run the Holden Alloytec v6 LY7 fully sequential.
I will upload a video of it running soon, just need to clean it up and add a cooling system.

Really wanting to learn the nitty gritty on how EMS work and to convert old dizzy + carby engines over to EFI and run a modern engines with open source ECU's. The end ...

Re: Throttle Boddy Driver

DBW throttle bodys have two potentiometers so I'm using one as a reface and one as current position when the positions equal each other the H bridge shuts off. I have done a lot of research since the original post. Their meant to be driven at 1000hz so i think the little nano can not keep up :(
