[@enlightendbel]

Finally someone who actually replaced those guide rods with linear rails instead of saying they installed linear rails but really only installed more useless guide rods. Gratz man and happy cutting! This confirms that what I was planning to do with the 3018 I ordered should work fine. Time to get to printing and milling parts.

[@flantc]

Very impressive!

[@JuliusCesar2781]

The milling head swings terribly. Isn't it possible to tighten it a little shorter?

Hola buenas estoy empezando en el cnc y quería comprarme está fresadora , quería empezar a hacer pequeñas piezas para motocicletas , mi pregunta es para que la máquina haga la pieza que la tienes que grabar en el software de la máquina ?

[@pierpaolop9534]

But this is not the 3018 pro.

[@guser210]

Was :)

[@pierpaolop9534]

@@guser210 Okay. How did you proceed with the modifications ?

[@guser210]

@@pierpaolop9534used the orignal 3018 to spot drilled the hole locations on the columns and the spindle base and holder and drill everything manually, that was the first upgrade, 2nd upgrade was a motor and mount, also spot drilled the holes since the old motor could not cut anything oustide of soft wood, but with the previous upgrades it made it more precised, 3rd upgrade machined all the parts with the upgraded machine. the upgrade also includes 2.1amp steppers and the spindle is contrlled externaly with a speed controller.

[@jamesgravel7755]

Ok so that’s a brushless spindle how did you change it to brushless. Using the original control board or a complete different set up?

[@guser210]

Is controlled manually via the power supply it comes with.

[@jamesgravel7755]

Ok thank you. I’m gona want to upgrade my spindle. I have a 500w but I’d like to upgrade. You did an awesome job on yours.

What diameter tool is that please ?

[@doctorgregg6847]

Great machine man. How did you fixed the stock to the plate? That blue thing is?

[@jeromesurffoil7033]

You apply blue painter's tape to the bed and the bottom of the material. Then you use CA (super glue) to adhere the tape to each other. When you are done milling, you can peel the tape off both surfaces. Cool trick!

Bonjour , elle fait du très bon travaille cette machine pour faire de l aluminium , elle est d origine ou modifier !! .

[@stephenlindsey9233]

Where did you purchase linear rails and how hard was the conversion?

[@guser210]

Amazon

[@guser210]

Purchased them about 8 months ago and the conversation was not hard I used the plastic machine to help me with the hold alignments and drill by hand, nice I had a rigid frame I redid the frame.

[@stephenlindsey9233]

Thank you so much! Do you feel that it was worth the upgrade?

[@guser210]

@@stephenlindsey9233 it was, the original machine was and is a waste of money

[@rzshss]

What are the Feed Rates, Depth & Plunge Rates?

[@guser210]

I really don’t remember what that was but the machine can cut 6mm axial 2mm radial at 600mm/m feed rate with a 1/4” endmill single flute. At 8000rpm

Can you do a vid on all the equipment?

Yeah but what do you mean all the equipment?

how are the MGN12 doing? ive heard they have no dust protection

[@guser210]

They are holding up well I mostly do Alumnium work with the occasional wood project here and there, I have dual air hoses to keep the dust from accumulating

[@Oliver_stick]

What is the original model and what were all the modifications you did and where did you find them?

[@guser210]

Original model genmitsu 3018, I don’t have the list of items handy but is 500W motor, HGR20 rails for the bed, MGN12 rails for Z and X, and SFU1204 ball screws for the X and Y.

[@Oliver_stick]

Oh thanks I appreciate it!

[@NINEWALKING]

By that time that ain’t no more 3018 and I guess for the costs one could have had another model. That all said this Frankenstein monster does work excellent. It ain’t the 3018 but it is awesome mini CNC machine finally. Good job.

[@BULLDOGG]

In name only.

[@Lancelot.R]

Ship of Theseus situation

[@imnota]

3018 is under 200$, next model up is 500$. This maybe has 180$ in mods and is definitely better than any off the shelf cnc under 500-600

[@SparkyBro-gt8wc]

3018 refers to the surface area.. but yeah. best upgrade ever.. my 500W spindle and mount are on the way. cant wait to get to work. In contrast.. it was this or a drill press with X-Y mill table. this costs way less. and a $35 offline controller. its just a digital drill press for aluminum plate now.

Only thing similar to "3018" is maybe the size. Your 3018 is way more rigid than a cheap Chinese version.

@@guser210 awesome, thank you. I'm "upgrading" my 3018 like you did yours and I think I'm struggling with figuring out the spindle situation the most. Do you think the rigidity/vibrations, the stepper motors, or the spindle is the weakest point right now?

@@samhoodak8075 the spindle neck on the original machine was the biggest source of vibration followed by the rail guides on the z axis and then the guides on the x and y.

材料どうやって固定してるのかな？

[@CharlesVanNoland]

Why are you dancing around with the camera like you gotta take a leak?! It's making me dizzy. Hold still, son! Cuts look clean though. I know it's not easy to dial right off the bat but the finishing pass, while it was great on the DOC, could've been shallower on the WOC. The longer area of flute engagement with material means more deflection (in a tabletop machine). I dunno if I would've broken the finishing pass into two, or just made the roughing passes go out a little further to thin out the finishing cut on the walls. Looks like it worked out really great though!

[@guser210]

You know how it is when you got to go you got to go… thanks for taking the time to comment and as you can see I am new to machining and that was my first cuts ever I’ve since come up with good recipes and continue to improve on them.

Your taking too large of step downs, you've got spindle chatter from a looze z and lack of coolant. But for what it is, this is awesome Save stock for for very light cut finish passes for better and flatter finishes
