Evening all!

Im currently running into an issue whilst trying to add a laser to my CNC.

Overview:

• Firmware Rev 3.3.0

• Workbee CNC running a Duet Wifi 2 with an expansion board for using heater 6 5v PWM.

So far ive used the following line and added to the config files -

M452 C"exp.heater6" R255 F200 ; Enable Laser mode, on exp.heater6, with max intensity being 255, and a PWM frequency of 200

Once i have saved this the PWM pin goes to 5v and stays there. Where am i going wrong with this?

Any help is greatly appreciated.

Thanks in advance

im hoping for some help with my firmware and some reccomended settings for an AM8. im running 0.9 degree motors on X &Y 4.8mH 1.6A, 2 x 0.6A 1.8 degree motors on z and 1.8 degree 1.2A for the E.

i was hoping someone could reccomend some ideal starter settings for the firmware.

This is my current set up

The system is running on 12V, would you reccomend going to 24V ?

Thanks in advance!

Thanks for your reply!

Ive tried using my old config settings from ramps such as the jerk settings etc but it doesnt seem to change. im running 128 microstepping could that be ruled out or would it not be that?

Hello, im hoping someone can point me in the right direction, im having an issue with blobs on the corners of my prints. I have tried all sorts of different settings to try and remove them like making the jerk settings much higher and pressure advance but still seem to be having issues. It looks like its slightly over extruding on starting a new layer which starts on the corner of the test cube. I will supply some images on this post.

I also have 0.1 of pressure advance on too.

Any help would be greatly appreciated!

thanks

Hey!

Hoping someone out there has already upgraded an anet 8 with one of these.

Having some issues with the firmware and was wondering if anyone has a working config file?

Regards

Looking for some help if possible

Im upgrading an anet A8 with this board and moving from ramps.

ive had a look at the reprap configurator and its quite different compared with the ramps.

Can the duetwifi be ran without a z probe? i currently just have a limit switch fitted. Also if i run in 256 do i need to multiply the steps/mm?

Thanks
