Ah yes, the P-DA board. Metered everything on that this past weekend, see my latest posts on “frickin laser beams” for more detail.
From what I have found, at least on the 60w is there should be plenty of headroom to power everything from the Lasertree brick. Assuming one came with your device. Plug it into the P-DA board and in the alternate output you can get 24V constant. I pigtailed a JST cable off that to power to Jackpot. Then you can plug the laser in and make sure the switch is in EXT mode so it uses the LT power brick.
So as long as the power brick is powerful enough, you can plug the Lasertree brick in 7, power the laser through 2, and should have 24v with enough left over amperage for the jackpot in 1.
Then any PWM and gnd from a 5V GPIO on Jackpot to any Input. Don’t have to worry about the 12/24V it asks for.
So… bought new belts, had a good sleep, and back at it…
The table is still a bit rough but I removed the trim and the old spoilboard and cut a part where it lifted under the Y rail
I decided to use 2 mdf plinths as “tracks" for the Y axis.
Printed a template using @franklyrosalind‘s Torsion LR4 table generator and used it as a guide to drill the belt supports holes and install the plinth on the existing table
Very happy with this, it’s nice and simple, and fool-proof
I aligned the plinth’s edge and screwed through belt holders and plinth into the table
Same process on the other side with a few bradnails to keeps everything in place
I drew a 1200mm diagonals rectangle in f360
Put some blue tape and burn some marks..
Measure the diagonals, put the numbers into cad, and you can see the skew
From my F360 calculation file I needed to back-off 3mm
Set the adjusting screw, put on some new tape, rinse and repeat until diags are both 1200mm
Small customization to celebrate…. Not a crown but hey….
Share a video of your laser cutting the strut plates please. Something I never thought of with the LR4 is being able to use a laser with temporary struts with no issues. Awesome!
