I even noticed that the software limit is not working properly in the controller(or maybe I do all wrong as usual) when I enable the software limit and setup all the traveling limits, the machine do the zero properly, and then the axis start traveling to the setup limit and stop, no other chance to move the machine then, what I'm doing wrong now? Thank you for any help you can give me before I throw the controller in the bin and buy a professional one

There was something like " ignore limit when home" in the limits menu? Plus i have programmed there to retract 10mm back, i think that was the default.

Now there is an situation where when homing overshoots the 0 and enters in the soft limit zone. What it does then is start to go into the another direction towards the other end limit switch.

Hence generally i find that it's a good practice to disable SOFT LIMIT when homing and then enable it again once homing is done. Or lower the speed of homing so it will stop on time. problem on a big machine like mine, cause you have to wait a lot. Or enter 2-3mm negative soft limit, but problem is that at 4mm it already will hit the sensor.

So i disable soft limit, home and then again i enable it. Anyway, i don't switch off the machine all day long.

On the first machine i have done i had the limits so that they will not interfere with the gantry, but on this one i decided that perpendicular position will give me better accuracy.

Problem solved thank you, was the over shooting that cause the problem, I just added a +/-0.5 mm to each axis and now is perfect, thank you!!

You've replaced a graphic with an alternative graphic?

That's "Modding" alright!

;-)

I would call this "customization", as i have no words to describe the original boot screen!!!
But i'm working on a very good graphic, so it will make sense then. This was just a trial.
A big thank to Benedikt for his contribution about the firmware, we hope to make this one "open source" soon.

Yeah great work you two are doing on this, I read the mad modder thread on it last night.

I wonder if Boyan has seen it yet ?

Mmmhhh, don't know , maybe not yet, in the meantime this is the better one, Benedict is going to include the design as default if possible, let's see how is going on in the next few days...
Cheers 🍻
