How many are you making? If it just one or 2 don’t wory about the time. If its a bunch work out spiritual pocketing speeds mapel has not been to much of a problem for me other than burning wit to slow a cut.
Oak is nice to work with too. A little. More forgiving also
367 holes to drill to 10mm.
It’s not the belts. The bit actually “wobbles” in the hole enlarging it. If it was the belts it’d happen on every hole but it’s random. It’s something I’d expect with a loose core but everything is tight enough that I’m not getting any movement in the core or trucks.
That’s a soul-sucking procedure, if ever there was one…

Are you using a ‘pecking’ routine?
A pecking routine will go down 2 mm, out 1mm. Etc. Etc. Until it’s at final depth. It helps keep the drillbit from just shoving it’s way through the wood.
Also. What rpm are you using? Smaller the bit, the faster it needs to spin to clear chips.
Yes, as stated with both a 1mm DoC and a 2mm D0C.

I’m not having issues pocketing. I can pocket with the 1/8" end mill just fine. But this is a drill operation. Trying to pocket cut with the 1/16" bit will take much longer. 4:34 to drill with a 1mm DoC on a 1/8" drill bit. 8:10 to helical drill with a 1/16" end mill.
I’m beginning to wish I had an ER11 collet. Then I’d be able to use a 2mm bit to helical drill. That comes out to half the time of a peck drill.
Doesn’t help I just realized all the holes in my plans are 3mm, not 1/8". That complicates a few things…
This says something is not right. Maybe the core is a little loose? Or the router? There shouldn’t be any wobbling…
With your machine off move your core and check several spots. It might be tight lined up on a brace but then lose between braces.
Later today I’m going to check the spots specifically where the wobbles happened. On top of that, the drill makes a horrible squealing noise as it cuts. Did it with the end mill, too. Doesn’t happen during pocket or profile operations.
I could see a 1/8" or 1/16" drill bit following the grain in a hard piece of wood and causing a wobble once it enters the wood. The router itself might not wobble, but the bit can flex causing what would look like a wobble.
Sorry. I missread your post and somehow attributed this comment to speed of cut not depth.
What z speed are you drilling at? Have you tried slowing that feed rate down a bit? It sounds like you have a bit of scrap maple at this point. I’d create a new gcode with just a few drill holes. On each hole, set a different z speed and see which one works the best. The slower you go, the less wobble you should get, but obviously there’s a trade off between speed and time.
Absolute worst case… use the drillbit and the CNC to just mark the hole locations and then use a drill press (if you have one) to manually drill all the holes where you have full control of the speed and can ‘feel’ the cut.
Shouldn’t happen either. 
I’ve had skinny bits wander in wood before.
It does happen and the reason for me using pocketing. In my mind the doing it once is worth it and is faster
Sounds like speeds and feeds are not right. Same sound as one of the interns trying to run a 1 inch endmill through hardened steel using speed and feed for aluminum.
Just my two cents
IDC says 17000 rpm at 25.4mm per second. I was running 17000 rpm with 3mm per second. Would that cause a problem?
Is there an easy way to change feeds in EstlCAM? As far as I can tell you can only set it to what the bit is. Change the bit numbers and it updates all toolpaths with that bit.
I did find that OpenBuilds CAM lets you set the feedrates on each operation. I’ve got a setup for peck drilling with slow speed and feed and then one for continuous drilling with higher feeds until reaching the 25.4mm/sec IDC recommends. We’ll see how it goes. Starting on pine then plywood before moving to the new soft maple I bought.
You can create multiple tools for the same one with different settings.
Yeah, what Philipp said. I have several of the same tools saved with different setting depending on what material I am going to run.
Faster and longer is better in this case. I drilled 95 holes in maple at 25.4mm/s 10mm DOC. Not a single oblong hole. Last test I ran was 1mm DOC at 3mm/s. Made less than 45 holes before the oblongs happened.
