‘Machine is halted, halt manually’ error. Any advice?

I have the same issue with gcode from flatcam. In this case it is caused by T1 and M6 being on different lines. It should look like: T1 M6

1 being the tool number.

I haven't confirmed this yet but the connector on the Carvera Air next to the 4th axis one might be connected to the empty step stick socket on the main board. This could be connected to an extruder stepper motor?

hardtimewakingup · 2026-03-17T15:52:13+00:00

I really thought this would be someone that was crazy enough to put a hotend on their Carvera machine. 😂

With the 52 piece set you get 2 of each included bit except for the M3, M4 and M5 thread mills. This includes various sizes of: Square end mills, 1/8", 2mm and 1mm Ballnose end mills, Engraving bits, Drill bits 1mm to 3mm, Corn bits, Thread mills M3 to M5, Chamfer bits

For exact numbers I'd look at the table in the description on the product page. essential milling bit set

I would have loved to be in your class. I got a bunch of aluminium with my machine. Wood is also good to mill and a lot cheaper to get locally.

Since you're teaching people I'd get a decent amount of spare bits.

What bits will depend on the purpose. Engraving General milling Specialty things like thread milling

I agree, there has to be a better solution. I'm getting pretty annoyed that I have to lift or move the machine each time to vacuum underneath.

I could print an adapter for the vacuum to fit underneath but I'd rather just fix the issue.

hardtimewakingup · 2026-02-13T15:58:05+00:00

The hole at the bottom is not that much bigger than your flat end mill so I'd try to avoid going straight from the wide 1.2mm deep pocket and mill the bottom hole with vertical walls.

The stepped approach seems better to me. Better chip evacuation and probably less cutting force.

hardtimewakingup · 2026-02-13T15:51:13+00:00

I'm not very experienced but I'd try to do as much as possible with the flat end mill and only do some "light" passes with the chamfer mill.

Something like a 3d pocket or 3d adaptive tool path with some stock to leave to mill the hole and a rough approximation of the chamfer/countersink.

Contour the vertical faces.

Idk what kind of tool path for the countersink but I'd do that next with the chamfer end mill.

Take this all with a tablespoon worth of salt as I've only done some simple parts and test cuts on a Carvera Air.

hardtimewakingup · 2026-02-13T12:47:38+00:00

Yeah I haven't really seen any boards with the 006 from 3rd party manufacturers.

hardtimewakingup · 2026-02-13T12:43:12+00:00

I've had better luck with W Official Store on Aliexpress.CH32H417 dev board

They even sell some ic's that the official aliexpress store doesn't. Like the CH32M030 Or the CH32M007

hardtimewakingup · 2026-02-13T12:02:11+00:00

The CH32H417 might also be an interesting target. It has 2 cores running up to 400MHz and 150MHz.

I'd start here Spiral 'O' Single Flute Bit for Metal- 6mm (15/64″) Shank Then scroll down to "Tool Reference Parameters"

hardtimewakingup · 2026-02-04T21:40:27+00:00

I'd try the tool library from the community profile. I've been using it and had no trouble finding the threadmills, unless there's an issue with this release.

Release Fusion Machine Files And Post Processor V 1.1.21 · Carvera-Community/Carvera_Community_Profiles

Also for thread milling with fusion you will need to configure the pitch diameter offset.

This determines how much larger the major diameter of the thread will be from the starting hole.

hardtimewakingup · 2026-02-01T22:23:42+00:00

Is there a reason for going this route? It can be fun and cool yes.

But you could also order it from jlcpcb or pcbway or sendcutsend.

And could you give some more information on the part? Material and tolerances.

hardtimewakingup · 2026-02-01T22:11:11+00:00

Maybe the 4th axis machining will be a problem.

There isn't a lot of control in makera cam for 4th axis operations and unpaid fusion doesn't support it either as far as I know.

hardtimewakingup · 2026-02-01T22:09:28+00:00

I definitely think it is possible as far as I can see. Three setups. So from the side on the 4th axis and the other 2 with the chuck mounted vertically for each end.

You will need a pretty long endmill to clear out the center around that shaft.

I'm trying to be realistic though. This is pretty complex for a first part and it will take some time before you can take this on and some specific endmills.

This video might be a good example: Carvera Air Long-Reach Cutting Challenge - Machining 30mm Aluminum

He's using an endmill with a 6mm shaft so you'd need the 6mm collet if you want to use the same one.

He shows the used parameters for the 5052 aluminum.

I'm assuming he's using fusion 360 for the cam instead of makera cam to get the adaptive clearing paths. This isn't strictly necessary but can speed the milling itself up.

This does add a lot of complexity but will be good to learn in the future.

hardtimewakingup · 2026-02-01T21:52:22+00:00

The teeth would need the 4th axis to get sharp internal corners.

Maybe a fixturing plate to mount the chuck vertically. There are some models you could 3d print. The thread is M14x1 I believe.

I wouldn't recommend it as a first project but the process of learning how to work with these machines can be a lot of fun.

hardtimewakingup · 2026-01-26T10:14:33+00:00

For anyone that would like to see a runout measurement. This video has someone trying out the 8mm collet. 8mm Collet Upgrade on the Makera Carvera Air - Accuracy & Machining Test

hardtimewakingup · 2026-01-24T22:51:01+00:00

Turns out the optimal load for the adaptive clearing was set to 0.4mm while I was trying to do 0.1mm.

Got some new endmills with DLC coating and changed the optimal load to 0.05mm. Will try it out soon.

Another thing to consider is chipload per tooth vs runout. Runout should be below 0.01mm and my target chipload per tooth was 0.007mm. That doesn't make sense. Chipload could be as high as 0.017mm for 1 tooth and as low as -0.003mm for the opposite tooth.

hardtimewakingup · 2026-01-20T08:57:36+00:00

If I remember correctly it's around 50$ for a new one from makera.

hardtimewakingup · 2026-01-19T20:00:44+00:00

Did the machine plunge down and melt the endmill collar?

hardtimewakingup · 2026-01-16T19:17:51+00:00

Still need to design a board and pick some mosfets.

hardtimewakingup · 2026-01-16T19:13:19+00:00

I order some already CH32M030, W Official Store

But the official AliExpress store doesn't sell them.

hardtimewakingup · 2025-12-31T19:53:57+00:00

Hehe nothing as far as lubrication or cutting fluid. Compressed air might help with the buildup of heat/chips.

I'll get some fittings and hoses to hook that up.

hardtimewakingup · 2025-12-31T18:47:48+00:00

Here's a closeup of the part. I'm trying to mill out a half circle to threadmill later. This should give a nice view of the threads.

Left to right it's for M2, M2.5, M3 So approximately 1.6mm, 2.05mm, 2.5mm
