Just ran into a issue i hope i can get a little help with. For some reasong my Carbide 3d router has decided to stop spinning. I was running a job yesterday cutting some parts out of thin aluminum sheet and thought i could hear a slight whining sound but everything seemed ok so didnt think much of it. Today when i went to start a new job i was changing endmills and noticed i couldn’t spin the spindle by hand, its as though its stuck in some way. I just dont know enough about these routers to trouble shoot the issue. Any thoughts as to what might be the problem?
If it’s a Carbide Compact Router try changing the carbon brushes — if that doesn’t work, or if it’s a VFD, check in at support@carbide3d.com
If you need to get cutting today, a Makita RT0701 is a drop-in replacement for a Standard Carbide Compact Router (uses the same collets, nut, brushes, bearings, &c.), albeit with a shorter cord, different control layout, dial which lacks detents and which may vibrate off a given speed setting, and in teal — a fair number of our customers with good relations w/ a local Makita dealer use them successfully.
Thanks for the quick relpy Will. First thing i tried was swapping out the carbon brush but it didnt help. I just emailed support with a video of the issue, hopefully its fixable. Good to know about thr makita router, i’ll likely pick one up if it looks like i’ll be down for a while.
If the router can’t be turned easily by hand, the bearings inside are most likely fused slag from what you’ve described. The router probably got pretty warm to hot while you were machining the aluminum.
You can get replacement parts if you want - the Makita trim router bearing parts are the same from tool parts distributors.
Thanks for your input. I try to keep a close eye on everything when cutting aluminum and i dont think the router or material was getting overy hot. After much trial and error feel like i have a pretty good recipe but what you’re saying makes a lot of sense. Any chance you know of any videos showing what needs to be replaced/repaired? Never taken one of these routers apart before.
I’ve never done it myself…there’s a few users here on the forum who have done it.
A quick search online yielded: Trimmer Makita RT0700C Repair (youtube.com)
The C3D router should be pretty similar.

Cool, i appreciate that. I’ll likely pick up the Makita replacement so i can get back to my orders quickly but i do want to see if i can fix my current one. I hate throwing things away if they’re fixable.

Here is the repair kit:
Not sanctioned by C3D, but it works and is quick.
Lower bearing is locked up. You can purchase replacement Makita bearing which are much better bearings and easy to replace with a cheap bearing puller. Don’t even have to completely remove the router from the machine,
Thanks for the link. I’m in canada so im likely better off just replacing the router for that price but good to know its an option.
Yeah ive been researching the issue today and the bearing going bad definitely seems to be the cause of the problem. Do you happen to know what the size/model of the lower bearing that needs replacing? Seems likes theres lots of options out there.

I’ve purchased a couple off of Ebay but I found this site that says they’re Makita OEM.
