Re: EZStruder synced with Z stepper

You probably have it plugged into the wrong port on the RAMBO, remember there are 2 Z stepper connectors next to each other that get the same signals.

Re: New Rostock Troubles

I did notice the two times that I unclogged it that I had melted ABS in the PEEK tube. However, the thermistor read that it was at the temperature that I wanted. If the thermistor is reading off, is there a way to correct for it in the firmware or something? This is indicative of too aggressive a r...

Re: Duet WiFi on Rostock Max update

Relative extrusion is somewhat overrated, I agree it's the better solution overall, but it's not a significant improvement because almost every slicer resets the extrusion to 0 at every layer change, so errors only accumulate in a layer. IEEE floats have 26 bits of precision in the mantissa so even ...

Re: Duet WiFi on Rostock Max update

Funnily enough I finally connected my Duet (0.85) to a printer over the weekend, and I have to say I was very impressed, one of the smoothest setups I've been through. Outside of the initial firmware flash and copying on config files to the SDCard I did everything from the web interface. I really li...

You have to pull it out of the board and test it with a meter, they don't look any different when they are blown.

Re: semaphore timeout period has expired

Be very careful with SD cards, they don't all work on the arduino based readers like RAMBO. They are required to support an SPI interface and not all cards do, and there is no way to tell from the cards themselves. The interface to the cards on the Rambo is pathetically slow (it's 1 bit serial) so I...

Re: Shapeoko or X Carve

I have an XCarve, I'd buy the Shapeoko if I were doing it again, in retrospect I prefer the X-Axis design, the XCarve uses 2 parallel extrusions, which makes it prone to twisting under load. There are a lot of end user hacks to stiffen the axis, but really for the 1000mm version it's just not stiff ...

I think they are 20x60 which is probably total overkill, the printers smaller than a Max 10 inch build plate and I think 12 inch build height. You could certainly use taller extrusions, I have no idea what brand he's using (if I had to guess I'd guess Misumi), I haven't seen it in the flesh yet, but...

Re: Color mixing ideas

There are machines doing many colour printing using a Diamond hot end and Duet electronics. See this claimed 300 colour print m for an example. The main issue seems to be that the Diamond doesn't mix the filaments very well. If we could sort that out, then I think we would be most of the way there....

Re: Hot end keeps hitting part and knocking it loose

Your probably slightly overextruding, It's somewhat difficult to see from the images you posted. The extra plastic gets pushed around by the nozzle, and it will later hit a high spot. Your better off slightly under extruding as a starting point. It could also be belts not being tight, as the head ch...

Re: Can't get below 1mm wall thickness

I'm going to guess you modeled something with a 0.5mm wall and the sliver is doubling up on it. Depending on what you are trying to print, if you just want a thin wall the best way to do that is create a solid object and set the infill to 0 and the perimeters to 1. Thin features are handled differen...

Re: EEPROM Settings and mins and maxes?

Auto tune I find to be about as useful as a random number generator.
It's usually an OK starting point, but I always end up manually tweaking the results, you can get <1C variation with some messing about.

PID stands for Proportional Integral Derivative, not Power Interval Damping.

Re: EEPROM Settings and mins and maxes?

From the source code it looks like PIDDriveMax is the maximum allowable PWM setting i.e. it clamps the output of the PID calculation.
PIDMax scales the output of the PID calculation i.e. it's some sort of normalization.

Both are 0-255 255 is always on for the PWM pin.

It's far more likely the wiring for the thermistor is shorted, or open than the thermistor being damaged. The most common failure I've seen is people breaking the legs. just disconnect the thermistor from the board and measure the resistance. Most of the time shorts are against the heater block, and...
