Max V4 Scaling problem

My horizontal scale is off by 1.5%. I just finished updating to the latest 3.2.2 firmware and recalibrated the machine, but the scale is still off. I edited the arm length in config.g, but that doesn't help. The config-override.g still has the wrong lengths in there, but the comments say to not edit...

Apologies for the long delay. I didn't get a notice that someone replied.
I am printing with Hatchbox ABS+. Bed adhesion is not a problem for me any more.

Re: Sampling Filament Compression Force

What you need is a load cell or similar sensor that measures the force that is stopping the Bowden tube popping out of the collets at each end. The strain gauge built into the HE300 isn't suitable because, like the the Duet3D Smart Effector is is based on, it is designed to detect changes in force ...

Sampling Filament Compression Force

Problem: My Cura projects have different settings based on the profile of the part I'm printing. If I turn on the fan at a low height, the plate cannot keep up with the loss of heat, and there is a much greater risk of part delaminating from the bed. So, for the lower heights, I restrict fan operati...

Re: Tech Support Needed on Z-Probe Always Triggered

I'm assuming you've got either a 3.2 or an upgraded 3.0... If the blue light is on during printing, that's ok. It's being triggered by the current induced by the heated bed - you'll notice if the head moves far enough away, the led will go out. You /cannot/ run the calibration while the heated bed ...

Tech Support Needed on Z-Probe Always Triggered

I submitted a ticket yesterday, but nobody has responded to me. My SE300 strain gauge z-probe has gotten to where it's almost always triggered, making calibration almost impossible. It's always on during printing, and when completely still, sometimes remains on indefinitely. I've raised the trigger ...

Not connecting to round circles

Rmax V3.2. I can't seem to get the interior walls of a screw hole to attach properly. I've changed flow rate, line width, speeds and temperatures, but I think this basically comes down to a slicing problem. Does anyone have any ideas?

I bought the kit to upgrade from 3.0 to 3.2. I must be an early adopter, because the instructions for building the whip are not complete. Does anyone have a picture they can send of their whip? I'm interested in each end.

Fan Speed

What's the purpose of minimum and maximum fan speed? I'm not seeing any variation during prints, except for bridging fan speed. Near the end of my prints, the tip of the part is very small, and heat builds up, getting very mushy. If I am watching, I'll reduce my nozzle temp and turn on fans to max. ...

Push in connector source?

When I build my RMax, I recall there being some .1 pitch connectors that accepted a wire. No crimping required, just push in your stripped wire and done. What is this connector called?

This is still a problem. When I print single parts, they are excellent quality. Multiple parts seem to have an occasional problem that kind of looks like under extrusion. I'm trying to add a picture, but it's not inserting after uploading.
