Re: Inside Profile vs. Pocket

If you’re using Fusion sometimes various profiles defaults to leaving material. That is a simple check but the idea is you rough cut then do a final pass that removes any material left during the rough cut. Sometimes the preview will show material being cut that is unwanted? At least see it before c...

Under Table Storage

I've built the bigger 50x100 wood stand for the KRMX02 and currently have a bunch of plywood and scrap underneath the bed. I'd like to have something more substantial, maybe even something that slides out for storage? Anyone using the space under the CNC for storage in a cleaver way - or useful way?...

Re: Milling Aluminum Long Board truck

Sure! I guess I have done enough where I can add some potentially helpful tips :-) For aluminum, my limiting factor is certainly the Bosch 1617 EVS router I'm using. It's been great for what it can do and runs like a champ, but it cannot mill aluminum in the recommended ways per many YouTube videos....

Re: Milling Aluminum Long Board truck

Got the board done! Finally. The electrical and speed control items were a big learning curve for me compared to the CNC work. The drop down looks cool but isn't providing enough clearance so I'm milling new aluminum extensions today to rise up instead of drop down. But the motorcycle helmet is on i...

Re: Milling Aluminum Long Board truck

"The difficulty will be getting a collet bit to hold it..." I ordered some ER20 collets for my Bosch 1617 but they don't fit. I thought I read online that the 1617 uses ER20 collets. After it didn't fit, I searched some more and read that no US router products use ER Collets? If I go the P...

Re: Milling Aluminum Long Board truck

Here is one example of such a drill bit. https://www.mcmaster.com/29355A19/ The difficulty will be getting a collet to hold it. I am not recommending this set, but it is but one example that contains a suitable collet for 1.5 mm drill bits. https://amzn.to/2M1UUVJ An option is a carbide bit like ht...

Re: Milling Aluminum Long Board truck

From what I've researched, a 40 Tooth pulley is about 64 to 65 mm in diameter. The resulting drill holes for the teeth are about 1.3 to 1.5mm in diameter. I'm looking to hold a 15 mm belt, so the depth might be 16 mm. I'm not sure where to find that type of bit with such a small diameter but enough ...

Re: Milling Aluminum Long Board truck

Thanks Michael - surprisingly inexpensive. I read a little about the use / importance of parallels so I ordered the one with the parallels. Should hold everything I need as a 3" piece is my widest stock. Looked into the Kurt vises but a little pricey for what I need. Design is almost done. Wait...

Re: Milling Aluminum Long Board truck

:D I was thinking about that! I’m surprised how low $ the aluminum flat bar costs. I will probably buy some larger pieces and use some symmetrical holes to secure it to the table and allow for milling both sides ... probably going to be large learning curve on this one :D

Milling Aluminum Long Board truck

Looking for opinions / thoughts for milling some long board trucks for an electric skateboard. Trying to use the experience to get my teenage son into machining and such. I have yet to do any aluminum milling with my KRMX02, but have watched the videos on the the Kronos website. Looks like 2 flute c...

Re: CNC Pyrography Experiments

That does look cool. Never heard of pyrography but apparently you can do it on leather too... That might be a money maker... never seen a leather shop / upholsterer with a CNC machine.
