Machine Purchase Guidance 2026 Machine and Service Sales

9 Upvotes

2026 thread with some changes, I have opened this thread for services. I am going to strictly enforce these rules this year.

READ THE RULES CAREFULLY OR YOUR POST WILL BE REMOVED

Rules:

Used or new-old items ONLY! - This subreddit, and this post is not to allow retail sale of Computer Numerical Control related parts. There will be no influx of commercial sales or anything like that. Repeat offenders will be banned.

Local Sale preferred - This is to protect both the buyer and seller. Shipping introduces other hassles, especially with CNC-related parts that might be large or weigh a lot. Personal addresses must NOT be posted publicly!!!. After discussing the deal, the two parties may exchange details via DM or other messaging services to meet up.

Pictures and Prices - The comment must include pictures of the parts with the poster’s username written on a paper, kept next to the parts. Prices must be included, along with the city, country. The buyers may post their offer publicly or via DMs.

At least a 6 month old Reddit account - Anyone posting any “For Sale” items must have a Reddit account that is at least 6 months old (NO EXCEPTIONS!), with at least some activity apart from the comment in this post about selling their parts.

Parts or Machines - Machines (working or for parting out), raw material, electronics (motors, drivers, controllers, switches/sensors, etc), hardware (machine tools, mechanical tools, profiles, pneumatic/hydraulic stuff, etc), fasteners, etc all qualify as parts. If in doubt, send a modmail. Machines include routers, mills, big-boy VMCs/lathes, etc.

Services - New for 2026 I am allowing quoting, to quote you must provide proof of real life, that is a picture of the poser with username and date on a piece of paper, ideally with some sort of machine tool or CAD/CAM in the photo to verify you are more than a dog with a phone.

The subreddit staff is not responsible if a deal goes sour - While we will take all reports of scamming seriously, the moderation team is not responsible for, nor can we provide any help. The buyer must do their own due diligence before meeting up the seller and exchanging money for parts.

After a successful transaction, the buyer and seller are requested to update/post their comment here. This will help sellers and future buyers in subsequent transactions with the respective seller.

The moderation team reserves the right to remove comments/items-for-sale at their own discretion.

Please adhere to these rules!

SOFTWARE Does anyone want this plugin?

I built a plugin for UGS that allows you to upload your step file and gcode and probe specific edges and features to reorient your model and determine XY origin. It also changes the GCODE axis in case your model is slightly off rotation.

Is this useful for anyone? I feel like UGS is super outdated.

OPERATION SUPPORT CNC Quoting

6 Upvotes

For those running CNC machine shops or handling quoting, I'm curious how you typically approach quoting a new job.

Do you usually start from scratch by estimating material costs, machining time, setups, etc., or do you look at similar jobs you've completed in the past to get a more accurate estimate?

Also, how useful is your past job history when quoting something new?

ADVICE Info on “Aegis worldwide”?

2 Upvotes

Posted on here a little bit ago about difficulty getting a career in the field started, just got off the phone with someone from Aegis worldwide, seemed to be very interested in me and I liked everything he was telling me, seems like the job would be some traveling to go and troubleshoot / repair machines especially CNC’s. From everything I’ve found online place seems great and legit and just wanna make sure I’m not jumping into a sharks mouth here. Any info would be appreciated

GENERAL SUPPORT Renishaw Alarm 1092 Unexpected surface found

2 Upvotes

I am running single surface touches with my renishaw spindle probe. I am using p9811 to do single surface touches. sometimes when i do z touches, it gives me the alarm listed in the title after the first touch of the 2 touch cycle. I have tried cleaning all of the glass, changing batteries, putting kroil in the base of the probe, it does not feel sticky, and I tried running it with the lights off. It seems to be pretty random, doesnt matter where I touch in z but it seems to be every 10 touches or so and it seems to be getting worse. Has anyone had this and solved the problem?

SOFTWARE SUPPORT Fusion 360 toolpath cutting into the model

Thumbnail gallery
12 Upvotes

Hi All, I am trying to mill the highlighted face below without cutting into the sides of the rest of the model, but Fusion 360 CAM is drawing a toolpath through the side walls. I'm using the 2D Offset Roughing function. I selected the face for the "pocket selection". The same thing happened when I turned off the lead-in and lead-out. When I shrink the maximum stepover, it preserves that overall cutting path and just makes more passes, so that's not it. I'm using a 1/16" dia end mill, and managed to complete the entire design except for this feature. Tried Adaptive roughing as well, same thing.

HARDWARE Just tried Amana bits

I heard the saw blades dove in quality years ago but had hope for the CNC tools. I broke two in 6 hours at the same settings I use for a Vortex, and it was a 3/8 compression end mill. Are they really that shitty, or is it possible it's a bad batch of carbide or something? I'm blown away by how bad my experience was with their tools.

ADVICE Any advice would be appreciated

9 Upvotes

Hello I’m new here I work for a company where I operate CNC machines using CAD. I went to school to learn machining I got the hang of manual machines but doing the programming was hard for me. I didn’t learn much and now that I’m working I have to. I do small tweaks in the program and the zero set I can do the basics like changing tools, moving it + or - x y z a, and change the speeds. I want to learn more I know I will learn more as I go but I won’t learn what I want from just operating the machine. the company doesn’t care if we know how to do the programing so if we have problems we just ask one of the engineers. I can’t learn how to make my own programs like that and they don’t have any way to teach the programming. Because all of the programmers don’t have a set standard and it gets confusing if they’re not here to help . I don’t want to learn to keep the machine running instead of fixing the problem. Is there any website or anything I can learn with to become a better machinist.

ADVICE I want to learn CNC programming at home (Sorry for my English)...

0 Upvotes

...I have a 3D printer, I read that it is literally a CNC machine.

Which software should I download FreeCAD or fusion360 for this? Where do I even start and how can a printer help me with this? I really want to learn this and come to work in Canada, I heard that citizens with this specialty are welcome in Canada. But first, of course, I need to learn this and get a job in my country.

I also have a computer with 5060 and 32ddr4, is this enough for CNC?

I'm a complete beginner, only a couple of times I made a drawings of home and parts in "Compass3D"

HARDWARE SUPPORT Gray Smelly Coolant.

2 Upvotes

I just replaced it like a month and a half ago, but we had some repairs so it sat stagnant in the shop all week.

Obviously led to some growth, now it smells like somebody took a shit in the coolant tank.

This would normally mean I'd dump the tank and clean tf out of it, but the coolant I'm running is expensive, and I'm paying out of pocket after just spending $9k on repairs.

Having never ran gray sewage on 6-4, how bad of an idea is it for another week until I can move some parts and replace the coolant?
