These parts move the placement of the power button and DC barrel jack on the positron 3d printer.
The power swithcing pcb is replaced with this drop-in unit I will be selling. After printing the parts you'll see the power button is placed on the right side of the machine and the secondary DC barrel plug on the left.
I will add a link as soon as it’s for sale.
You are able to now hotswap the power supplies with a usb power bank or between a UPS or a battery if your on the move. This mod is also compatible with the internal power supply modification as well. As the left side of the machine is left completely empty.
For the USB C VERSION ONLY:
this is the board I purchased and tested. it does provide a 28V out which the positron is capable of running. I would not recommend using this on other machines or projects since they may not accept the higher voltage.
For any of this to work you must have a usb bank or plug that is rated for 140W usb 3.1 PD
I have an anker prime powerbank 27,650mah bank. But there are many other options available.
Please find the usb PD board for sale SOON. Thanks for the support!
DISCLAIMER: This mod is at your own risk you are dealing with 24-28VDC any fires, injuries sustained while performing this modification are done at your own risk.
Some other upgrades from origional parts,
Larger cooling intakes
proper exhaust port
Direct cooling duct
front mounted power button
opens space on the left side of machine for other parts
NOTE: If you’re not using the internal power supply, then don’t print the ac in rear left panel. You can keep the original stock dc barrel one. The power switch will need to be moved to the front.
UPDATE:04/12/2026
There is a delay in production, the board is getting a full redesign due to thermal concerns, also I want to make sure its safe for people to run all the time in their machines.
