Thanks for the reply, i measure the Molex Crimps outside of the connector before the Molex in and there were fine, i had no clue how to meassure inside the connector.

Hi there,
i installed an smart effector to my Duet in an Anycubic Predator with Magballs.
I have issues with my Hotend Cooler, its way too slow to cool it.
I meassure the Voltage all the way from the Duet to the cabel and the Molex Connector which goes in the Smart Effector and had 24 V there.
But At the Molex Connector for the Fan itself i meassure 15V. So i m stuck, what could be done to solve this except of connect the Hotend Fan directly?

facepalm feels like an idiot, doesn`t see that. Redefine the offset in G31 and everythings fine now. Thanks!

@dc42 No, even after the new Installation of the Firmware isn't there a deployprobe.g or an retractprobe.g

Tried it again, Setup Firmware again, Homeall works like a charm. Start G32, first start point should is defined in bed.g as X40 Y40 but he tried to move to X-90 Y-90? What am i doing wrong?

I run the FW 1.21 a couple of weeks, two weeks ago i changed from IR Probe to Orion. I first thought i made a mistake at my config.g yesterday, so i build a new one today. As this didn`t worked i made the FW Update to exclude an Firmware Issue.

Then i thought something on the Board is broken but G30, homeall and homez worked as they should.

Dont shure if this also is a part of the problem, but my last 3 Thermistor and Thermistor Cables made Heater Faults if the cable is moved in the wrong way...

No the error started at FW 1.21 and i did an upgrade to exclude an FW error. also G30, Homez and homeall did work but G32 and G29 doesnt do whats in bed.g or in M557

No, i had the problem since yesterday and didnt use a BL-Touch. I had an Orion and before an IR Probe. Just updated today from 1.21 to 2.0 and made the config complete new but both changed nothing. There aren`t deployprobe.g or an retractprobe.g in my sys.

My G32 and my G29 doesn`t work anymore. Homeall works fine and in the directions i had defined. But if i send an G32 to the Duet my Hotend crashes against the front left motor mount.

I tried this with FW 1.21 and with FW2.0 Set up the config complete new today and define also Minimum Axis to X/Y 20/20 and tried to define the bed.g at X40 Y270 at first point even then it rushes against the motor mount.

I don`t had a clue anymore what to do exept of throw my Core XY out of the window
