In my experience, it is a good idea to stiffen the top beam.
I use a simple laser pointer attached to the beam in line with the beam, pointing to the wall.
Ideally you don’t want to see the laser dot move on a wall at 5 feet when the sled moves around the workspace.
Up-down move in the center will show front-back bow flex. Left-right move at constant height will show the tips vertical flex.
Cut the final sled this afternoon. Here is my impression and observations:
- Automated processes like this are awesome!
- 1 round thru calibration, and a successful cut. I consider that a victory.
- Note to self: dont forget to change the safety z height to something besides .5 inch
- My temp sled sucked. It was rough and the boards surrounding my sled wood was rough so it would drag on it and rotate the sled making the not perfect ring alignment more pronounced. (I think anyway)
- Overall impressed with the maslow!
- The cut on the final sled went real well. Some imperfection but great really. I think the sled caught the paver hold down on the last cut and broke it free making the bit dig into it.
- Thanks to everyone for contributing and for the very thorough instructions!

Fit everything to the new sled today but didn’t get to cut. After hanging it I noticed a screw in the floor, it was to the z axis coupler! The other screw was loose as well. Maybe thats why it messed up the paver hold down.

I was curious and wanted to do a quick test to see how it performed in the corners so I cut a 40” tall by 88” wide rectangle .1” deep. It did great, no wandering at all. 1/8” width difference between top and bottom so I think I’ll do a recalibrate with the new sled. I also need to move the center pulleys more midline, when in the top corners they ran out of string. Other than that it did awesome.
maybe you can see the rectangle in this pic.

Did a test cut today to see if I could successfully cut a pocket with raised text inside. It was almost completely successful. It didn’t cut the inside of the A for some reason lol.
Other than that I am super happy with it. Nice and clean! Using 1/8" down cut spiral end mill. I think the kind of darkish part of the pocket is just the ply of the plywood, not burnt.

Bought a Vivitar security cam at Menards on sale for $25! It works great! Now I can step out into the other room for design work etc. Image and sound is available 24/7 day or night from anywhere thru their app. So far its worked perfectly.

Please add infrared detector, smoke detector, have a fire extinguisher in reach and be aware that your insurance will not pay a dime. OK, I might have exaggerated a tiny bit, but from my opinion MaslowCNC is not a machine you leave alone. You can do some sanding of parts next to it, but a app -> wireless -> relay -> Emergancy Stop is not a solution.
Kind regards,

I here ya. Dont worry too much. I’m super paranoid and watch/listen close and am not gone more than a few minutes. A infrared detector would be cool though!

Does the CAM show a path inside the A? Usually if a small pocket is skipped it is because the tool is too large to fit in the space, so the cam skips it.
Looks great, though!

I think what happened was the inside of the A wasnt selected as part of the pocket. Things like that are why I did the cut. I tried to select it separately and do a profile but it didnt happen.

Project of the day - little plaquething for the wife. She has a tattoo just like it (but better lol)
It seems like I always forget one setting or another. This time I forgot to set the depth. It only cut about 1/2 inch of the outside border instead the full way thru. I thought maybe change the code and run just the border again since it was in the home position but wasnt sure if that would work so I sawed and sanded.
I’m impressed with the Maz! Big machine but still great precision on this small pocket text. One pic is right after finishing without any cleanup. After the sawing and sanding I finished with danish oil.

Todays shop time was to finish a project. Made a sensory panel toy. I cut the main panel, and the plane props and some of the little pieces on the Maz. Took longer than I wanted but the Mazlow did a great job.

I like seeing the beginning to in progress pics and knowledge. Thank you for sharing. Makes me want to get started using mine. The beginning set up looks daunting though, very technical.

Depending on your comfort level with things, it can be. Read, read, and read some more and hope for the best.

I am (what might be considered) challenged when it comes to tech. I may have had to do each step more times than the average home made CNC builder but I did it! I’m currently trying to switch computers so back to some challenges but you can do it.
I have more confidence.
My friends are impressed.
My wife thinks I’m smarter…
