Thanks Chris! I’ll play with it in the next few weeks and let you know if I have any issues!

Hey @chrismakesstuff I wanted to see if there was a version that would support Auto Square as well as SD card support for Macros?

Thanks

I had downloaded and tested the firmware a while back and it didn’t work. Can’t remember now what the issues were. I have since moved over to a FluidNC controller, that is very easy to setup autosquare and macros on SD. I hope you folks move toward keeping firmware and software open for customization. I was disappointed, for example to see that the SLB has a Y limit sensor port that was disabled. The Altmill is a pro level machine and customization will be important moving forward, particularly with the 4x8’. My two cents.

@wiremonkey that’s a shame it didn’t work, I’ve had around 5 others say they had it all set up right and was working well. Glad to hear you’re doing well on FNC, don’t worry we’ll continue making our stuff open - our Firmware is all public already and I actually have some guidance on it for how to make your own build, but I’m happy to also provide some customized versions for those who don’t feel confident doing it themselves. FYI the Y sensor port on the SLB wasn’t disabled, it just needs to have the auto-squaring firmware installed to utilize the feedback on that port.

@Sparky1, speaking of which sorry it took me a bit before I had the time to get to it but I believe I’ve compiled a new firmware together that has both NGC expressions and auto-squaring that I’ll attach here: SuperLongBoard_B5.0.5b-as.hex (823.3 KB)

Be careful trying it out, since it’s been a bit since the last time I compiled, and if I missed anything it might cause unexpected machine behaviour. If you’re ok with the risk, try it out and let me know how it goes :+1:

Hey Sparky,

I’m curious how you have your limit switches wired up? I’m considering repurposing my z inductance switch as a second y and replacing the z with a mechanical rocker.

If you have a sec please describe your set up and post a pic.

Thanks,

Nat

@chrismakesstuff Is the SLB currently in the store flashed with the auto squaring firmware?

Here’s the most accurate way to square and set your $171 for machines with Dual Y homing sensors (eg Altmill)

Note for AltMill, Y1 is on the left side of the machine.
