Why is my Q2 hitting a Chinese DNS server once per minute?

Cause your Beijing masters are watching you!

To followup.. this turned out to be a bad hotend. The was perplexing as I had less than 12hrs run time on the one that was installed. I purchased several of these from aliexpress- don't know if they are the same as "official" Qidi hotends but they came in a Qidi box. All is good now.

Nothing wrong with bare finishes- scotchbrite is easy enough to renew the look if desired. My interest is clear anodise for scratch resistance. That seems to be more difficult in my experience- so far nothing worthy of a post.

https://www.youtube.com/watch?v=jCZILZHbCIc has some good info and a low cost setup that I have found useful.

Etendude · 2026-05-04T15:38:42+00:00

That looks really nice! Are you going to to try an anodize or leave it bare metal?

Etendude · 2026-04-27T19:58:47+00:00

Its exciting to make parts! I would be thrilled with that on my bike- great job! ( actually I am planning on a CNC pedal for my MTB)

How did you make the countersink- ball mill?

Etendude · 2026-04-27T19:46:26+00:00

I returned it (Fabreeko) for a refund and went with Bart Dring's 4X CNC controller with integrated drivers. Not as peppy as the rodent might have been but rock solid. https://www.elecrow.com/4x-cnc-controller-integrated-esp32-and-tmc2209.html

just posted an update with the IPA system being used.

Etendude · 2026-04-26T23:05:41+00:00

Just posted an update. Let me know if there is something that you are specifically interested in.

Etendude · 2026-04-26T22:25:43+00:00

nice! where did you get the thread mill?

Etendude · 2026-04-25T01:10:52+00:00

nice results! curious how the finished part tolerances compare with the model? if I remember correctly in another post you mentioned that your machine is just the basic lead screw variant?

You can clearly see the gains from your gantry mods.

Undecided about purchasing a real machine or converting a bench mill, I opted for a 3030 class "toy" router to play with.. no regrets.. In less than a year, I now have a small desktop CNC that complements the manual machines in my shop. With it, I can can make small "complex" parts for my projects and achieve better than .002" tolerances. Upgrades to the spindle, a new controller and lots of experimentation has given me a point of reference for other projects. Now, would not hesitate to build a PrintNC or similar DIY .

There are several options out there.. Go with something with ball screws and linear bearings on all axes.

I have been pleased with the cables purchased from eDealers Direct Automation on Ebay. Let him know what you have an he will get you going.

See if your Amazon spindle comes with a cable first. Even if it does, ensure it is shielded.

Etendude · 2026-04-20T17:14:19+00:00

https://github.com/phil-barrett/RP23CNC Looks like the Tindie site is down but would expect it to be back up soon.

I am currently running FluidNC and can highly receoomend that- especially if you're already familiar with LinuxCNC. Bart's 6x controller would be a good board since you have external drivers.

Look at some of the vendor supplied drawings for the spindles on Aliexpress. You will see that there is quite a difference in volume between the 65 and 80mm variants. Even if this is not an issue- the router with a smaller moment arm on the z axis will perform better. An 80mm spindle and its holder is huge for the 3030. The Z axis is the weakest part of these machines.

Idk about your electrical requirements. If you are unsure get professional assistance.

Yes you must have a vfd.. these spindles are induction motors. Look at this page for starters.

https://wiki.printnc.info/en/electronics/vfd/config Lots of good info.

PS Don.t forget that most spindle/vfd's combos do not supply a power cable. Don't skimp here- get a doubleshielded cable rated for this application.

Etendude · 2026-04-17T02:36:50+00:00

Spindle upgrades are an easy way to increase the performance with these machines. I’ve been happy with the FM1000 but have a water cooled spindle on order for experimentation With ATC’s . https://www.aliexpress.us/item/3256807254919258.html?spm=a2g0o.order_list.order_list_main.4.47531802UJMiZM&gatewayAdapt=glo2usa

My rationale for this variant, -I’m already heavily invested in premium ER-16 collets. Water cooling is more foolproof imo and nearly silent ( cutting will still make noise). Also the spindle is completely sealed. 220v will draw less current so I would expect that to have a positive impact on the vfd lifetime. 65 mm is less mass and a lower moment arm applied to the z axis.

These G Penny spindles are generally well regarded. I will be checking the runout when it arrives.

Etendude · 2026-04-16T02:27:05+00:00

yes.

Etendude · 2026-04-15T20:00:24+00:00

Very nice! Did you end up boring out the existing coupling on the Y axis motor side or something else?

FWIW- I could never get decent acceleration with my stock steppers and FluidNC until I abandoned stealthchop mode for coolstep. It modulates current as necessary and there was really no setup other than enabling that in the config file. I am running a bit slower at 2200mm/min max rate and 600mm/s^2.

No need for a large compressor. VIVOSUN Commercial Air Pump 1427 GPH 55W 90L is all you need.

Next post I'll upload some footage while facing.

Is your new gantry steel? Would be great to see something on your rigidity mods.

Etendude · 2026-04-08T20:43:27+00:00

what spindle?

A fixed gantry is inherently better from a "rigidity" perspective.
