Welcome to the world of CNC! :) So I had originally bought the letter pack on Etsy from DIYWeddingMarket and they supplied the SVG & DXF files that I could load into my CAM program. I did make one modification to the holes and replaced their basic round holes with my design to hold the light socket perfectly. As far as tips, Compression bits are 100% worth it. Just remember compression bits should never plunge into the material, it needs a zig zag/ramp lead in feature. Use conventional milling (right hand) when cutting contours/profile cuts in wood. It is entirely possible to cut a single full depth of cut on a 1/8" compression bit through plywood and MDF. The GWizard program that calculates feeds and speeds is a life saver to figure out those feeds and speeds. Looks complicated to a newbie though not gonna lie. First projects that I started out doing, simple signs. Pocketed out letters and a simple contour sign cutout. Then got into Vcarved signs. Let me know if you have any other questions.

Just measured, it's 4mm thick

This was the kit I purchased. Came with the whole laser head assembly, mirror, lens, the motor driver and the sensor control board. lightobject.com/real-time-auto-focus-laser-head-rtaf/

I have 4.5KW (Model A) ATC Spindle ISO30 220V from NewCarve. I only had one issue within the first 3 months and that was the top fan died out. I didn't bother trying to get it replaced over warranty so I bought a new fan & replaced it myself. www.aliexpress.us/item/2252799820443576.html?pdp_npi=4%40dis%21USD%21US%20%241%2C438.00%21US%20%241%2C222.30%21%21%211438.00%211222.30%21%402101ea7117349033081231428e377f%2112000043182962113%21sh%21US%21127237761%21X&spm=a2g0o.store_pc_allItems_or_groupList.new_all_items_2007550666904.1000006758328&gatewayAdapt=glo2usa

EDIT: So the issue you're referring to, the skipping, yeah it was the parameters issue. Shortly after though, which I don't think I have updated you on, while that did fix it, I started getting my Y2 servo drive faulting out due to "over heat" (the shop was COLD af and the driver was cool to the touch.) Wellll I kinda didn't fix it. I had thought I did, cause I switched out servo drives (I had an extra from my router build). That new drive worked ALL weekend until I tried engraving something. Exact same issue happened, the new drive faulted out to "overheat". Odd behavior. Same exact settings as Y1 driver. So I think I'm going to swap the entire Nema 34 DMM-Tech servo system to regular AC closed loop stepper motors/drives from Automation Technologies Inc and hold these servos for my PM-940V milling machine I'm about to order before the new year. I have the closed loop stepper system on my 4x8 router and haven't had any issues for the past 4 years so I'll make it work. Servos are more of a headache to be honest, especially with a gantry machine and the need to auto tune 1 motor at a time with the DMM Tech servos.

@@TylerHarney Thank you very much for sharing your experience Tayler 👏👏🥇🥇, that helps us all to know what can happen to us when we build our own machines, I really appreciate it, your designs also help me think of things to implement on my machine, thank you very much for all your tips Tayler, I don't use servos, but if I use them thanks to you, I already know the possible problems I may have. Keep it up, Tayler, as always, congratulations ,have great success with your future creations and have a Merry Christmas.

@@Mekaproyects <3 MErry Christmas Meka!

I didn't think about that on this project, but I like that idea! I'll have to keep that in mind for the future. Thank you!

While planning that out I realized that if I left that extra extrusion overhang I could remove that 1st mirror which would make the beam pass through and I'd mount a laser head at the end of the extrusion. Then I could mount a 4th axis rotary chuck allowing me to cut cylindrical pieces along the Y axis. I've got the rotary chuck but haven't yet started the design add on yet.

I had plenty of them this past weekend. It's weird, everything seems to break or mess up when I start recording. Thanks for checking out the video!

!! I did take notice of the screen with the failed file. I didn't think anything of it except it was just super weird and I kept debugging.

I would agree. I do have plans on covering the beam path.

I used the Fusion360 sheet metal feature to design the box. Then for the bends I lasered as a perforation.

Ha ha! I knew someone would say something 🤣 I've made much progress since this post. Let me upload my newest video I took this week cutting the same cardboard boxes. I stripped the Masso controller, the entire gantry and designed a lower center of gravity gantry with a servo belt drive X axis.

2 flute, I just used a cheap amazon bit. I bought 10 of them cause I didn't think they were originally up to the task. amzn.to/3Zpmobf

Thank you! I want to remake it out of some baltic birch. Then the small pocket tags at the bottom of each tool will be a dual color 3D printed ## insert. Version 2 might be cool if it was fully enclosed with an acrylic front window. Then you have a staging tool holder at the front of the machine where you put your tools for that particular program you are about to run.

No, You'd be better off buying a CNC router to cut those dashboards. You would need to stick to aluminum. As far as steel, a plasma cutter CNC could do the job. As far as cutting steel or aluminum using a fiber laser, those machines start at at least $20k and use 1.5-3kW of power. 150w-300w CO2 laser can cut carbon steel but you're still looking at $25,000. The tubes alone could cost $4k. Hopefully that helps. A cheap CNC router using the correct endmill cutter and feed/speed could get you started.

This is the bit I use. It's a compression endmill so I can take a single pass. amzn.to/48z46qX

If you want to first try a bit that's cheaper that cuts the same, amzn.to/3NOSMgv

Shoot me a message over on my website under the contact section. I'll be able to accommodate.

Thanks! This was a project I did for Lollapaloose Chicago 2024, I design/fabricated a pair of high top Charging Tables for Coca Cola with a 3 tiered Govee lights around it. Ha, it is an interesting word. Yeah I've had absolutely 0 issues with the taller gantry. Now on my second machine, I have the taller gantry and extended, I do notice a very noticeable wobble. The only difference in the frame, I see, is my first machine uses the steel 45 degree leg supports and my second machine uses the aluminum 45 degree leg supports. I do have servos on the second machine so that could be making the difference too. DMM doesn't have a way to tune the two gantry motors very easily so I'm kinda guessing.

Thank you, Thank you! I do notice an increased amount of available power with this tube only firing through the lens and bypassing any type mirrors. I'm pretty excited :)

I'll take some more videos. I designed a 1/4" steel tube mount that bolts to the AVID Z axis plate. The power supply is mounted to that tube mount. I also stiffened up the back of the Z axis assembly. I turned some steel down to create a mount for the lens head. I'm using Masso's Pin 11 PWM output, pin 12 turns on the air assist which is plumbed in from my compressor. I DO have some noticeable EMF that may drive people away from the project. I'm not sure if it's the way I have the signals set up to the laser power supply or because I have a 110v power cord running through the machine up to the laser power supply or if it's Masso's PWM output issue. I cut my first 1/4" acrylic parts last night and am super impressed with the edge quality despite some noticeable vibration from my 12" gantry height. Either that or my servos need further tuning. The edges were super smooth, these were rectangular parts tho. I do plan on cross bracing the legs as well. It's weird, my first avid is much more rigid than this second one.

Don't remember, but probably 1600 steps and whatever amperage that motor was rated for.

Maybe, if that ever gets done. Focus has shifted to the 4x8 laser at the moment. I'm doing this same set up for the main CNC router. Since that laptop is on it's last days.

I believe it's 8mm max diameter.

Sorry for the delayed response, You could remove the direction signal wire. I'm pretty sure that would only make the motor move one direction.

Hey J, Most likely the microstep settings

I think so.

No way, what? lol
