Shhhhhh ASMR will distract… time will fade and I will be in kobalt bliss
Or I’ll just eat the butt load of candy I have leftover from the tricker treaters

Did you start running a thermal test 30 minutes in and needed to block the reflection to get more accurate readings? Or was that blue tape just for me

Yep, exactly that…

Brushes get hot, so ensure clearance/air-gap |
Here’s some stills until I release Part 3 of the ~200 Part Kobalt Router review series.
Planning to print the mount using PETG since the router body was getting up to ~48C.
Hot brushes makes sense, but was surprised how hot the collet/business-end gets. I’ve never FLIR’d a Router before, will compare with my Makita…

Please do. My makita got hot the other day ~110°F close to your kobalt. Would love to find out that it wasn’t something wrong with my build or the extension cord I used. The dewalt though. That one had issues, it had to hit 150°F as it melted away the thin wall in the mount.
RIP to my third pla mount

Question. Did it ever exceed 48°C or was this the final running temp?
So did some diving on other cnc forums and sounds like it’s a new trim router thing. That the new ones can be hit or miss on whether or not they run hot. Some say the heat is no issue. Others are being cautious.
Further into the rabbit hole I go the more people think it’s the lower bearings transferring heat to the shaft. It’s worth noting that some of the overheating issues also seems to be electrical issues such as use of long extension cords, or an overloaded circuit. Maybe try the test in your normal cnc outlet too.
Yep, 48C was the highest I remember seeing. Vaguely recall final temp being slightly cooler than max for some reason. I’ll reply back to this post if I discover otherwise when going through the footage.

Ok. I will spill the beans:
It’s a router! Made by Kobalt! With a picture of the Low Rider on the side of the box!
Goodnight.

I looked online at my local (25 miles away) Lowe’s at it showed 4 in stock. After hearing comments about this not being true at other stores, I called and asked an associate to put eyes on one for me before make the trip. When he didn’t find them where indicated online I suggested he look in receiving. Sure enough he found them there. There were 6 of them, not 4 ss indicated online. Good news! Not so fast, my friend. They were on a pallet with other Holiday promotional products that was marked with November 8th. So he could not pull one from the pallet. So I ordered one online and it arrived yesterday evening while I was at a neighborhood Halloween event grilling hotdogs to give away.

My Makita gets that hot if it runs for like…1 minute.

Their inventory system is always off. I know if I want something I have to make sure they have at least 7 or get them to grab it
Did you end up printing your mounts out of petg? Stuck with the pla? Like I stated above other CNC forms have mentioned new router have a heat issue and the theory is it’s the lower bearing but that’s usually where those threads end. Most say it’s fine but a couple have fire concerns. Someone said like what Ryan was saying in yours that they need to be broken in. If it is the lower bearing maybe it grinds away enougg metal to bring the heat down? Has your resolved or is it still running hot?
Still runs pretty hot. I don’t know if it is still quite as hot.
After that, I ran my router for like 10 minutes at speed 6 one day just to try to break it in a little, but I haven’t checked the temperature as closely.
When I changed my mounts to the adjustable one, the mounts I pulled off were definitely deformed, but all I have is PLA to print with, so my mounts are still PLA.
If I only run the first part of a job for like 30 seconds to a minute, the collet is uncomfortably hot when trying to change bits.
I haven’t really had time to mess with it these last few weeks, so I still don’t know what the solution is. My gut was to return the router and try a different one, but I probably fell out of that window already.
There have been mixed responses with Makitas. I hear you are not alone with a hot bodied Makita after a short run time. My Makita does not get hot, but the Bauer gets hot. Must be a special run of them that get hot, but not all of them. Others have said, “Break in the brushes and then it will be fine,”
but I’m not sure how that is best accomplished. Since the brush area is the part that gets hot, maybe you could be the guinea pig and just swap the brushes and see if that fixes it? I suppose since the Bauer came with a spare set of brushes, I could try that on it as well.
Even funnier is that Lowes is a grocery store in North Carolina AND a home improvement store too.

Most say it isn’t an issue obviously with pla it is but the limitations stop there. The issue with returning is that you very well may get another bad model. This issue seems pretty widespread. Hopefully the kobalt doesn’t have the same issues and we’ll have a reliable base to go to.
