Building my own 5050 at the moment using a modded 3018 to make the custom parts, always enjoy watching new designs for ideas, cheers for the great videos.

I've just ordered one of these (Black Friday Deal!) partly because of your excellent review here. I'd also like to thank you for responding to all the various questions people have put to you, which i have also found very useful. Great KZfaq - Thanks!

Perfect. Great to see this. This is pretty much the upgrades I had planned for my 3020.

Glad to see that there is finely some smaller machines coming in with some more capability

Oh man, now I'm crazy about this beauty here. Your video make me so excited that I decided for this incredible machine!

Very informative. My unit is due for delivery later this week. Looking forward to your spindle upgrade videos.

Nice thorough review! Your build video of it enticed me enough to buy one for myself a few weeks ago. It's a great machine, but I've already found some ways to upgrade it: The stock spindle is good, but mine had a fair amount of runout in the motor shaft. There is a small amount of adjustability in the set screws of the ER11 tool holder, but I wasn't able to get mine low enough to be satisfactory to me. Additionally, the shaft deflects quite a bit under load, causing chatter. I ended up upgrading it to a 600W Deadelus brushless ER11 spindle. So far I'm really happy with that: it has a very small runout, and the ER11 tool holder is machined out of the shaft of the motor, so it's nice and stiff. There is very little deflection under load. Also, the collet nut that came with it is heaps better than the stock spindle's. I'll be looking forward to your video about your spindle upgrade! Another big issue with the WM-3020 is, despite having ballscrews, there is still an amount of "backlash" introduced by the lack of proper bearing mounts. I had read about this being necessary on DIY CNC forums but I wasn't really sure why until I got my machine. When a force is applied in the axial direction on a ball screw, there needs to be something to take that load and prevent it from sliding (you want the ball screw nut to slide, not the entire ball screw!). On the WM-3020, this force is taken in one direction by a flange-mount bearing, and the other by the bearings in the stepper motor. None of these interfaces are made rigidly, they are all slip-fit. Unless there is some preload applied (which there wasn't, and I think it would be hard to do) you will be able to shift the entire ball screw in and out without it rotating (ie. your axis will slide when it gets pushed towards the stepper motor). I solved this issue using some thrust bearings and machined bearing mounts that take the load instead of the stepper motor's bearings. For some reason the machine came with the GRBL setting "step idle delay" set to 25ms. As soon as an axis hasn't been moving for more than 25 milliseconds, it will turn off the stepper motor. I don't think this makes any sense for a CNC machine. For a lot of toolpaths, the Z height isn't changed for a long time. With this setting left at 25ms, your Z-axis stepper will turn off and upward or downward forces will cause your Z-axis to shift and you will loose those steps. This is a lot easier to happen with ballscrews than with lead screws, which have more sliding friction. You will also almost always lose whatever microstep position you were holding before it was turned off. I highly recommend disabling this feature! I'm still discovering ways to improve the rigidty of the machine (for example the plate that holds the Z-axis stepper is a little thin, and flexes under loads in the Z-axis), but overall I'm extremely pleased with it. I am looking forward to an increased Z-axis height kit (If I don't make one myself first...). That would be very nice because as it is currently, as soon as you add some fixturing you run out of extra height to install your bits!

Thanks for the followup vid on this machine! :)

As a good teacher,I appreciate your time

I like your video style a lot because you are going straight to the point. But provides still a lot of information around the topic. Two additional topics as a dedicated video would also be very interesting: 1) Attachment methods: o According to material: Aluminium/wood o Scotch: I did not yet understood why there is no double sided scotch used. Instead this "special" green one is used!? o Primer/Glue/Scotch method: I saw this method a lot but did not yet understood its main advantage. o Turning the machining object for maching its sides. Correct referencing after unscrewing the machining object. o Vises: Important aspects of them. There are cheap and expensive ones. What makes sense to invest for such a type of machine? o Egalization/Parallization(?) of four machining object faces? 2) Mills / Cooling: o Which coating/mill base material for which working material? o When is cooling required? Which types are when recommended? (I saw your video "Sainsmart Genmitsu 3020 Pro Max" which already gives some details) o Flute types: Single, dual, etc. When to use which? o Material removal/Surface finish: Which mills are recommended for material removal and which are good for a smooth surface? o Operating depth: What has to be considered if you want to create deep pockets? Say 30-40mm? Is it the mill cut depths only? Or more the Z-axis stability? Maybe you do a video with a bit more complex (40x40x40mm and ) wood/aluminium/steel objects and go into the mentioned aspects above a bit more in detail? Thanks a lot!

Did you ever add the more powerful motor

Great video - thanks :) Alu cutting performance seems hugely better than Genmitsu 3020 Pro Max

Great video! Very informative!

The y-axis linear rails and ball screw axis is exposed to dust and aluminium chips. How much dust/chips is still going into the rails/ball screw axis with a dust shoe? Which other means are recommended/required to avoid fast wear out of the rails/axis? In your video of the "Sainsmart Genmitsu 3020 Pro Max" you added some DPC material at the bottom of the table bed as a dust shield...

Can't wait to met mine tomorrow to mill aluminum

Beautiful Machine thanks for the video good job.

Nice video. I like the part where you make the PCB for the HY VFD. Can you tell me if these are available for sale? I just bought two of these machines and I have 65m 800w spindles with the HY VFD. I would like to control them with something like the board you created. Please let me know and if there is something available. Nice job, Marty

Im gonna try and put a 2hp HF router on mine when it shows up in a few days. Grabbed a foxalien 3018 for 299 with everything

I have subscribed after watching this very interesting machine. I am not in a hurry to get a cnc machine but I await the upgrade vid for the VFD spindle with higher power.

I have been thinking about purchasing this machine. Will it handle aluminum well also if I upgrade the gantry to steel plates do you think that it would help with ridgity? I am thinking of different ways to upgrade this machine? Or if you know of any other cnc machines that are already built well enough to handle aluminum and stainless steel could you point me in the right direction? Thank you for all you time in the videos you make.

Nice worki love that green color but what's the ral code?

Are the ballscrews locked in the bearing support or are the linear forces on the ballscrews transfered to the stepper motors?

I bought this machine, how do I learn to go from parts in CAD to Candle?

When you talk about 'optimal load', are you referring to the pitch at which the milling cutter advances?

A great review - what was the grade of the first pieces of aluminium that you did the test cuts in please? 1050?

great video, i've been referencing it a lot. What post processor did you use out of fusion 360 for your wm3020? I'm having trouble with consistency from fusion tool path simulation to what the program looks like after posting

Hi. What type of aluminum profile has this cnc? Thank you

Which would you recommend for aluminum and hardwood projects using either a dewalt/makita or 1.5kW spindle: WM-3020 or ProverXL 4030. Is this machine a lot more accurate compared to the 4030? Are the Nema 17 stepper motors of the WM-3020 a major limitation? Thanks!

Awesome review! Just ordered mine !! I was looking to get the 800w 65mm spindle but was wondering if you get any flex on the z axis or does the machine feel solid enough along with the nema 17 to handle the weight of the spindle?

Nice looking machine. A bit small for my taste. It would be nice if it was expandable or if they offered a larger version.

How does the sound compare to a genmitsu 3020 while milling aluminium ?

God damn and not a second too soon. Definitely gonna have to get one of these, I can see this being my templates machine especially with a router upgrade.

Hello. I also bought such a machine. How do you work on the machine if the spindle speed control does not work with G-code commands? I also do not adjust the slider.

@techydiy Have you ever tried to produce circuit boards for smd assembly with this type of machine?

great cnc under 1k

is this similar to the genmitsui 3030 prover max? this seems to be a better spec?

I’m having a hard time cutting aluminum. May I know where you get the air blower system? Could you please let me know? Thank you

Is it more important to have more RPM's or more Power on a trmmer/ router such as the makita ones

Does candle supports a possibility for a tool lengh sensor? To measure only a new tool after a swap in between a milling process

can fusion 360 be used to model and send G code to this machine? Or do you have to write the G-code manually?

How did you connect the air nozzle?

Does it have ability to cut and craving carbon fiber sheets of 1.5mm?

Where do you buy the endmills you use? Is it safe to buy the cheap no name ones?

Do you know why theres a y2 stepper motor port?

Have you had a chance to upgrade the spindle on this?

how long did it take to cut that angle bracket?

Is the promised video with the spindle upgrade still planned? Any ETA?

Hi, Do you have a link for the 65mm spindle mount? Thanks

Hi, please advise me, I only need to cut 3 mm copper sheet. What machine cheapest and suitable? CNC or laser cutter?

Hey. What pump and stuff you use as air blower?

Would this handle 12mm 7075 t6?

Oh people make like her

Looks like a great machine, but waaay too expensive!

why not cut fluid ? at least water

2 degree helix did not work at all on my machine had to change it to .5 degree

Similar to the 3020 pro max I think

Isn’t it the same as Sainsmart’s?

so much money is put in this unit and yet still using a cheap brushed motor and can't afford to use a brushlessed one ?
