Re: Cherry Pi III Is Available
@andy thanks a lot. the spring i am using are 7mm with 0.8 mm wire which is 60mm long. I will get a set of stronger springs and try again.

It should work with the spring you have, just add more tension to it... You need to remove the arm, pull the cord a little and then "push" the arm into place... the spring will now be loaded with good...

Quotewuz Sure, its just code, but then you only have one LED. I had one sensor not firing as a small piece of PLA got stuck next to the sensor, and I would have had a harder time to figure this out,...

Marlin and clay paste extruder (skiping)
Here's the problem I'm having with Marlin and a clay paste extruder . My geared stepper motor running the extruder pump seems to be giving out when I reach hi steps per mm on the feedrate and or...

It is the current that needs to be set correct. The voltage to the DRV8825 just needs to be high enough. What is the current rating of the stepper motors, and how high do you have the stepper motor...

A thought just occured to me. When printing, is there ever an issue with the FSR triggering, thus signalling that the hot-end has hit the bed, even though it might have just pressed down on the part?...

I wonder if brake cable (steel braided wire) would work in this situation? It should not stretch much at all under the loads a 3d printer can generate. Unfortunately the bend radius is large for those...

Endstops are ignored while printing. If you plan on only heating one area, it will need to be boro, otherwise you will break the glass.

You may be hitting maximum step frequency of Marlin for extruder. By default it is about 40 kHz. Based on your picture you can reach 600x600 = 360 kHz.

End stops are ignored while printing. Did not know that, thank-you. Though I will need to double check Repieter as that is what I am using right now.
