Which facility are you using to set the laser PWM: E values on the G1 commands, or M3 commands between the G1 commands?

Either way, you first need to make the E1 heater output (heater 2) available as a GPIO pin by sending M307 H2 A-1 C-1 D-1. After that:

If you are using E values on the G1 commands, send M571 P2 If you are using M3 commands, send your M452 P2 command after that.

Nice printer!

Best wishes 😉

Not sure where you're located, but we have both in stock here in the US (Filastruder).

@flopo:

I would need some help please, when I print for example a 20x20 cube everything's fine but when I print a round piece, tube etc… it's quite small.
For example I printed a 6mm diameter tube and when it finished printing I measured with the caliber and the result was 0.5mm smaller.
Why?
My printer is a Delta, with DUET WIFI, smart effector and magnetic rod.
Thanks in advance

As others have said, it's fairly normal for circles to come out small. A lot of it is to do with how printers handle curves. Basically slicers can't do true arcs so they simulate them by using lots of small straight line segments. If you take it to extremes and imagine a circle with only 6 segments, you get a hexagon. If you then measure that hexagon across the corners you'll find that it is the correct diameter but if you measure it across the flats, it's much smaller. You just have to make allowances for it and adapt the model to suit.

I've solved it. I made an autocalibration with a piece of paper folded three times. Weird, but it solved the problem. Now the height is correct and it prints well.

@Willy510:

Try putting an M82 not M83 in your start code and that should fix it

Yeah works…..I haven't thought about it....damn.....Thank you
