A friend told me he would like a CNC to make surfboards , and when I saw some videos of the lowrider, I had no other choice… order a kit, get some plywood and stainless tubes cut, run my printer non stop for a few days… and voila!
I was surprised how smooth a built it was, with everything assembling and working as it should at the first try… almost
Main points of the built:
1800mm * 800mm * something like 200+.
table surface dropped ~100mm compare to the wheels to hold the polystyrene blocks and accommodate the extra long bits.
SKR Pro1.2 and screen
500W cheap spindle.
150mm x 6mm flat end 4 flutes upcut bit and 100 x 6 corn end used to remove foam faster as it’s stiffer.
I generate the G-code with fusion which work great with flyfisher604 post processor.
In the video, you can see some sheets of paper in front of the lead screws to avoid the polystyrene to get in… I’ll design and print something to replace that. Other improvement will be to use the airflow from the spindle to blow the dust away.
I also need to fine tune how fast I can push it… 3000mm/min seems to be ok was long as the cut is not more than 3-4 cm deep with 3 mm stopover.
Only issues I had was not being able to connect with my Mac via repetier as it was not seeing the board, but worked great with a windows laptop.
Last remaining issue is the random freeze in the middle of a cut. And the only way to get it restarted (as I saw on the forum) is to plug in the laptop, connect with repetier and it restart fine until the end.
Did anyone found a fix for that?
I’ll be sad to see her go though when I’ll deliver her (yes it’s a her: such an artist!) …
