Good evening gentlemen
Today I reached a major build point. I have finished printing all the parts including the midway X & Y axis supports.
I have also drawn a cutting schedule to be able to make a custom build board for mounting the MPCNC. Tomorrow I will go and arrange to have the wood cut, I have decided to use 18mm MDF as it is a very stable substance. 3″ X 2″ to make the underneath frame. And also some 3mm sheet as a sacrificial top board. I will then most probably have a short delay while I wait for the rest of the compiments to be delivered. ☹️☹️
I did a test fit of the Router mount today, it goes together so smoothly and looks very impressive. Once again THANKYOU Ryan.
have a great evening,

Hi all, another one from the UK here. Found this thread looking for stepper motor advice and glad it’s an active one!
S Sauntson – Where did you source your stainless tubes from? You also mentioned getting a bunch of the hardware as a package, do you remember where from?
And finally, what am I looking for in a stepper motor? I’ve been looking at the links in the parts list and they reference motors with different currents – V1 shop being 4A and Amazon showing 2A, is that a factor or am I just looking for torque? There are so many options on Aliexpress!
Not intending to hijack the thread ^^July 19, 2018 at 4:08 pm #64185
Firstly Welcome, we’re getting a small group of Brits together now. I am still relatively new to this forum and the main man is Ryan. He is the generous guy who gave this project to the masses.
I got the SS tubes from http://www.metalmaniauk.com
I paid extra and had them cut to custom lengths and my CNC with have a workable area around 900mm X 600mm. They did an awesome job at cutting them and were so precise. When the tubes arrived all I had to do was remove a few burrs from around the ID.
The Hardware I was referring to were mainly the nuts n bolts. Apart from the SS tubes, I sourced many items from eBay. I did a few days of research before I placed my orders. I guess they will be the slowest to arrive but it gives me time to prepare the printed parts and read the assembly instructions.
As as for stepper motors, I went for 84 oz.in steppers. From the pages I read torque was important with motors connected in series at each end of the X & Y axis. These were the ones I settled on
As I have experience of modifying 3D printers I went for an all in one control board along with some nice upgrades along the way.
Have you started printing yet? I really have to say, Ryan as done a sterling job on the files. It goes together so nicely and so far as caused me zero hassles.
P.S I’m in Cambridgeshire…….

Very helpful, thanks! Shame the stainless is 25.4mm as I was planning on using 25mm screwfix conduit and then maybe replacing it at some point with stainless. Although (thinking out loud here) once you factor in spending £25ish on a pipe cutter for the conduit then it does make the stainless pre-cut stuff a lot more attractive.
I haven’t started on the prints just yet as I’ve been banging my head over why my printer is misbehaving and only just noticed that the plywood base it was on is super warped. I had already started replacing the extruder with a bowden style E3D hot end (thinking that might help solve my problems) so I’ll wrap that up first.

to have the stainless cut, packed and shipped it can to just over £90. I consider that a bargain although they turned out to be the most cost percentage of the project, to have them do all the cutting and I just needed to unpack and install saved a lot of time / hassle
if you have any other questions leave them here and I’ll do my best
regardsJuly 20, 2018 at 3:09 am #64224
Looks like my total comes to £70ish though I’m not going as big as yours and some I’ll consider cutting myself with a grinder as it doesn’t make sense for some of the smaller pieces like the feet parts being £5ish each cut to length or you can get a 50CM length for £5.84. Haven’t put the order in but thinking about it. Conduit is looking like £32 plus whatever for the pipe cutter (call it £20). Or maybe I have a go with the angle grinder. Decisions decisions.July 20, 2018 at 5:12 am #64234
I prefer using a hacksaw. I put three boards together to wrap the pipe (like a U) and I cut a slot with my table saw. Then I put in a pipe, line up the mark with the table saw slot, and the hacksaw cuts very straight down the slot from the table saw. If you’re going to spend 20, then get a hacksaw, because it’s so useful otherwise. If you don’t already have one.
You don’t have to build the jog, but I think it was worth it.July 20, 2018 at 6:12 am #64242
toolstation pipe cutter with spare blade £14.95
Just cut my x2 screwfix conduit 25mm lengths with it.July 20, 2018 at 6:21 am #64246
I hear what you are saying and totally agree it would have been so easy to have used my hacksaw. By having the tubes cut for me, I was assured that all lengths would be matching. Yes, I know with alittle time and patience I could have got the same result. I was just being a Lazy Brit ??
Today my Steppers arrived. Yay! Have checked the wiring and alls good. They took one week from Hong Kong, Now that’s quick for Free P&P via eBay!
I also just had all the wood cut by my local Jewsons just now for my mount board, yes I know they cut them all for me again but this time for £0 and they used their machine, saved me having to get my table saw out and the put it away….. They also did them while I waited.

I wasn’t judging you for having them cut, I just was recommending a hack saw over those pipe cutters. Those pipe cutters don’t like me.July 20, 2018 at 12:49 pm #64292
well not much else done today as I fell asleep,
also as its a Grand Prix weekend I’ll spend lost of it in front of the TV

The more of this project I constructed the greater the attention to detail shines through. I have constructed the centre gantry a few moments ago and it is a thing of beauty.
Every part is so beautifully designed, this would make an intriguing table model….
Slight adjustments to a few fasteners and it runs like silk.
One question is, are the no. of items correct, because I have four extra bearings and two extra bolts that I cannot find a place for.

That lighting makes it look so dramatic!July 23, 2018 at 12:07 pm #64523
Well a few more parts have arrived recently, some belts and threaded rod,
The weather today here in the east of the UK as been unpleasantly 32′ and because our driveway is surrounded by tall trees and bushes the temperature in the rear garden hit 39′ OUCH!
anyway, between pints of cold fluids and sitting down, I’ve made some progress
ive made the MPCNC bed out of 18mm MDF, the rails are made from laminated MDF, either two or three thick. I decided on MDF as there should be zero warping and used a whole sheet of 1220 X 2440 18mm MDF.

Damn. Seeing the finish on yours almost makes me want to reprint all of mine. Almost.July 23, 2018 at 3:36 pm #64554
I am just behind you by a few hours,gantry done all printing done including router mounts for a 400w chinese motor.
I am making the 25mm version and have used 53 bearings and 43 m8 nylocs.
I am following your thread posts and really enjoying it.July 23, 2018 at 3:59 pm #64555
Thank you for your kind words. It’s a pleasure doing this for the forum.
i am still attempting to print my Router mount, because of where it will be placed, I need to have suction sorted or I might end up single again ?
In the end I have got a Makita clone with 710watts of power, from research I did, they suggest changing the nose bearing for the Makita one, I have this already and apparently many spare Makita parts are a fit for the one I purchased.
For those interested a Zen 710watt Palm Router £31 off eBay
I can see myself ending up with a CNC spindle but for now, this Palm router will suffice. I have also looked at a focusable Laser……..
Im hoping tomorrow is a little cooler, but the forecast is its not playing ball. All I need now is the last five parts and the end push can continue. I’m still needing the controller board.

I am well impressed with how the prints turned out. I put it down as stated earlier to the updates to the XYZ Da Vinci V1.0 Printer, on the right below
Thank you to everyone for your kind words and support

Good Evening Gentlemen
With the temperatures here in the UK being excessive, I spent the day doing some tidying in my office to make space for my MPCNC.
Good progress made on both tidying and the next step.
Ive not locked everything up tight at the moment but doing the angles the measurements are im very pleased to say millimetre perfect.
I have left a 150mm space at one end to mount the electronics. The steppers at present are not installed as the wires sent were incorrect. Ho hum!
You will notice that I have installed supports midway along both X & Y axis.
see picture below
Any advice or comments welcome
Attachments:July 26, 2018 at 4:14 pm #64751
its been rather a quite day here today, nothing new from postie. Fortunately it worked in my favour as after I installed the stepper motors, I found that I had installed all but one of the corner pieces wrong. duh! A simple case that most men are afflicted by RTFM (read the F*****g manual)
Luckily I found my error and 30 minutes later is was sorted
I am hoping the stepper motor wires will arrive tomorrow and then I can solder them together and install them.
I have spent this afternoon Drawing a Controller Enclosure. Have decided to install a 12v fan in the lid and vents around the edges to keep the controller cool with good air flow. As you can see from the picture of my design.

today was a strange day, temp rose to 38′ and then this afternoon we had thunderstorms and heavy rain. It last 20 minutes and then became very humid.
Only a slight progress today. Having attached the Stepper motors recently and then decided to check everything before starting my nemesis, the wiring. Well with diagram in hand, a bunch of new stepper extension cables next to me, I took the plunge. Not a quick process with my panic testing at every stage, but the X-Axis stepper motors are wired, installed and tested. Yay!
Have placed outer covering and ended this with heatshrink. It’s just before 01:00 and I’ve been on it since 20:00, I must admit, I did it three times as each time I found a neater way. Dam my OCD ?
I am hoping the three remaining parts arrive very soon.

Wiring for the X & Y axis has been finished and tested. I still have to extend the Z axis Stepper Motor lead but that should just be a cut and solder exercise.
I enclosed the wires in protective woven covering and personally think it looks neat and tidy.
My conclusion on the wiring is, with alittle time and patience it is nothing to be concerned about. I did all the wiring as stated above with a diagram in hand and simply just followed it.
not forgetting to ignore wire colours but for connections only
