I was in the 8th hour of rough carving a flag with the marine emblim when it started carving about an inch over to the right stopped the carve, need to know what needs fixing please
you can see the top of the sergant strips that it has another top an inch over.
Please check the machine mechanically:
- Pulley set screws: http://docs.carbide3d.com/shapeoko-faq/shapeoko-3-how-to-check-the-pulley-set-screws/ — be sure to check all axes/pulleys including Z.
- V wheels / eccentric nuts: http://docs.carbide3d.com/support/tensioning-eccentrics
- Belt tension — the Z-axis should be guitar string tight (but careful not to bend the motor shaft): http://docs.carbide3d.com/assembly/shapeoko/xxl/step-5-belting/ on deep cuts it may help to remove one spring from the Z-axis temporarily (which side doesn’t matter), esp. if one hasn’t added a spoilboard on top of the wasteboard — it also helps to install the router as low as possible (installing the Makita adapter upside down will help). Some folks have found it helps to remove bolts which won’t stay tensioned (M4 Z-axis tension bolt, various V wheels with eccentric nuts), apply a thin bead of threadlock along the length of the threads, then reinstalling. See the video at: https://www.youtube.com/watch?v=_lIIb_PdziA Note that the X-axis motor is held in place on standoffs and if those bolts are loose this can cause belt tension issues.
It is also important to be sure that the collet is correctly tightened, the endmill fits correctly and doesn’t slip, and the router is mounted securely in the mount, and that the mount doesn’t shift. Note than endmill pullout can happen gradually, especially when profiling against tall walls.
Also feeds and speeds may be a consideration — the router speed setting should match the feeds and speeds for your selection of endmill and material. Please see:
(there’s a row matching dial settings to RPMs at the bottom)
There’s an interactive version at: https://public.tableau.com/profile/willadams#!/vizhome/Carbide3DCNCFeedsandSpeeds/Sheet1?publish=yes
Note that the feeds and speeds calculations in Carbide Create were updated for trim routers in 433 and 440 and later use a curated set of feeds and speeds which are stored in CSV files.
See https://www.youtube.com/watch?v=S9bceJxpqG0 for concepts on this and see the series #MaterialMonday: #MaterialMonday on YouTube for specifics.
You should test feeds and speeds in a piece of scrap using the technique at: https://precisebits.com/tutorials/calibrating_feeds_n_speeds.htm
Another consideration is Climb vs. Conventional Milling and tooling engagement — where possible avoid slotting and add geometry and cut as a pocket (Adding geometry to cut as a pocket with a finishing pass ).
Extensive discussion at: Origin/consistency of chipload recommendations and https://shapeokoenthusiasts.gitbook.io/shapeoko-cnc-a-to-z/feeds-and-speeds-basics with a spreadsheet for this at: Speeds, Feeds, Power, and Force (SFPF) Calculator
Will,
Where there is a Will there is a way…LOL
yep set screw was gone out of the x axis had ordered a maintenance kit just last week because of a broken belt, well the new belt I installed was already getting tore up it has steel belt, any way to make long story longer put new belt and pully with set screws…ty lost another belt, wish I knew where to just get one of those…
The belts are commodity item, for the Z-axis:.
- SDP/SI carries a 516mm belt: https://sdp-si.com/products/timing-belts/gt2.php
- http://www.robotdigg.com/product/501/520-2gt-6+endless+belt
- http://www.sdp-si.com/products/belts/gt2.htm
- Amazon
For lengths:
Well more bad news the replacement belt I got in maintenance kit stretched, ruined the logo
this was second piece, I installed final belt 3rd, 1st belt was my fault “set screw was missing” the second belt was faulty, I am praying this belt is fine, I had about 20 hours already in this, starting from square 1
Weird…
While you are addressing this (with support I guess), you could order some steel-core belts, or Kevlar belts, in parallel, just in case.

I was just wondering where I can get some belts , do you have size or a link,ty
If you’re under warranty, contact us at support@carbide3d.com or buy the Maintenance Kit, otherwise, Gates GT2 profile 2mm pitch 9mm wide (or 6mm wide 520mm endless) belts are available from specialty vendors such as SDP/SI or BB Man.
The only time I’ve seen belts fail like in your picture was after slamming the carriage pretty hard into the end stops - makes me think it might be a bit overtightened to begin with?
I hear from Will that SDP is a good source for genuine Gates belting, which is fiberglass only, but they’re a fantastic manufacturer (and originated the belt design) . - I’ve been meaning to try genuine belt and try that.
Here’s what a simple amazon search shows up:
https://www.amazon.com/s?k=9mm+gt2+belt&crid=1L650QG3NJUEN&sprefix=9mm+gt2%2Caps%2C171&ref=nb_sb_ss_i_1_7
9mm wide “gt2” (2mm tooth). Available with steel core, kevlar core, or “standard fiberglass”. The lengths are pretty much “cut to fit” - An XL takes about 2.5M of belt (give or take), an XXL will be more.

TY Nope I am no where near under warranty, is the maintenance kit warranted?
Because these belts where just purchased in the kit, if not no problem, carbide has been nothing less than top shelf.

I wonder if these were just bought from a kit, they will give you warranty on that kit
