Re: Delta-Pi Endstop Problem in Repeteir

Hi Tyler,
Can I just cover off some basics with you first.
What brand of stepper drivers are you using? (Some brands use different sense resistors and require different voltages)
Are you using 0.9° or 1.8° motors? I used 0.9deg/step motors on the prototype and I found that with 1/16 microstepping the pulse frequency exceeded what the RAMPS could output.
What micro-stepping setting are you using?
What steps/mm did you calculate?

Now, I have been using Repetier firmware 0.82.2 IIRC
Recently I started trying out Johann's Marlin fork to get the bed levelling.
I still prefer Repetier but I have had both working.
One thing to be wary of with the stock delta code is that there is no inadequate limit checking and it is possible to send the head to unreachable positions with unpredictable results.
But I don't think that's what happens in your case.
I have seen this slow down though in my own printer. unfortunately I haven't seen it recently and I never found the cause.
I've made glacial progress on my printer since march but the good news is I have 2 weeks of vacation coming over Christmas and new year and the Delta-Pi is top of my list.
