Great write up! Really sounds like you have a great handle on what you've gotten yourself into and the limitations of the K-40.
Yeah, I've been reading about the K40's for a few years...but stayed away due to the limitations. But, at $300 I couldn't say no and figured the limitations would make for an interesting project
I have plans for a drop in exhaust filter (using kitchen scratch pads for the filter material) I'll pass them along to you if you want.
(It does add some to the clearance behind the machine though.
Yeah, I'll check them out. Still debating where the machine will live long term and what I'll do for exhaust. For now it's in front of the back patio door and the weather is getting nice so I can just run a vent through there...but that won't be a permanent solution.
Curious how you plan to handle focus (raise lower the bed.)
I haven't decided yet. I'm debating building a motorized bed vs. just a fixed bed. I don't play on cutting a wide variety of materials so adjustable focus doesn't seem like that big of a priority. Just something I can fix at the right height for 1/8" material since that's mostly what I plan on cutting with it. But even then I'm not sure if I want to do a needle bed, honecomb, something like a bigger version of @dkj4linux's popsicle stick surface....I'll figure something out...just need to get it moving and lasing before I worry too much about it.
Congrats on joining the "Lazer" crowd!
Well, I did have the small laser on my MPCNC already But it is nice to have a "real" laser now
Didn't get a whole lot done last night. Finished printing the foot inserts and installing the new feet. Did some practice crimps with the new crimpers (so nice having real crimpers, but still take a bit of practice!) and just took it easy. My ammeter did arrive - but there's no appropriate hole to install it in. So tonight I may grab a scrap of wood and cut a new temporary control panel.
Still no word from uberclock about when my smoothieboard will ship Not very happy about that. Almost a week later and still not shipped. So...I gave in an ordered one from Amazon after I noticed that the seller on amazon is an authorized reseller. They also include all of the connectors and the 5v regulator which the official source doesn't. I figure the second board can go on my printer or MPCNC when it finally arrives.
