Hi! Thank you for the info and descriptive video. I wonder, now that you have it for some time, how do you find using it? Is it good enough compared to how your Optimum mill would be if it were CNCed?
I am very satisfied with the machine. In fact, it turned out better than I expected. Unlike my old green router (as you mentioned) it cuts steel quite well. But there is always room for improvement: What would I change if I built it again? Next time I would use this spindle: www.damencnc.com/en/quicktoolchanger-fan-c5160-d-2dbs-hsk40c-pr-hy-2-2kw-6-000-18-000rpm/a3969 It has three times the torque than my new Teknomotor spindle. The new 2kW Teknomotor spindle I'm using was an improvement, but there are some torque issues when drilling. (I can't use drill bits larger than 5mm in steel for drilling, for milling I use carbide endmills up to 10mm)). A big advantage would be quick tool changes since using collets sucks. What else? Automatic lubrication would be nice, glass scales for higher accuracy (LinuxCNC can read them and correct division errors). Since the gantry is rock solid (even stiffer compared to my MB4), I would opt for 50mm taller columns to achieve more Z travel. I started converting a second MB4 to CNC that I bought used at a great price on Ebay. But I immediately gave up when I realized that an MB4 would only provide less than 200mm of Y travel and has a spindle that is far too slow for aluminum - even for steel using modern carbide end mills. I'm definitely missing some sort of chip guard - but I don't want to waste too much shop space on a large greenhouse. Maybee I come up with an idea for this sometime. Ok - that has been a larger comment. Hope that helps! Or feel free to message me! Greets Markus
@@RUNCNC thanks! it actually helps a lot. I am considering getting an old CNC, a Maho MH400E, which I guess compared to the MB4, has 4000 rpm. The issue with that is the greenhouse...so 2m*2m*2m, which indeed sucks for shop floor covered. Alternatively, building something as you did seems a good option, the issue I see is the lack of rigidity and capability compared to a bit iron machine. Curious how you see that.
- surfaced cross beam - surfaced left & right ‘legs’ I had some problems with making a flat surface for Y rails, but finally I managed to remove 1,5 mm of steel and I have a flat ~90 x 20 cm surface.

@@TheHalloweenmasks Did you check for additiononal play in your bearing blocks? To check this, you put a dial indicator to the end of your ballscrews and apply some force to them.
There was play there but I fitted a second ball screw nut with preload, I still have small backlash so I compensate for this within the cnc software.@@RUNCNC
Danke! Ja, Baustahl ist billig, leicht zu bekommen und 3x so biegesteif wie Alu. Wenn man es nicht selber überfräsen kann, gibt man es halt weg. Das ist auch nicht so teuer!
@@RUNCNC Ich habe meine Anfang des Jahres aus Aluminium gebaut. Bis jetzt sehr zufrieden damit. Habe allerdings auch noch kein Stahl zerspant :-D. Aluminum aus dem vollen macht Sie aber ohne zu meckern!
excellent work, I ask you some questions: 1- which motor do you recommend, step motors or servo motor? 2- what machine did you use for cutting? 3- what type of drill bits are used for different materials? 4- which is better, arduino or mach3 controller Thank you so much.
1 - I would go for servos, because they perform better than steppers if you tune them right. 2 - for sheet metal I used my cnc plasma table, construction steel was cut using a band saw 3 - on the router I only use carbide tools 4 - I have no experience with arduino. My plasma table works with mach 3, that's fine. Nowadays I'm very satisfied with linuxcnc.
Ok, now I am building a clone of this. Stay tuned. My progress is around 40% - CAD drawings - giant cast plate - metal sheets - cutting - welding - annealing - milling Z and XZ plates - sourcing motors, spindle, rails and ball screws … I am here …
Hi, Can you please tell me which spindle you have used and also would you recommend it. I am part way through my cnc build and am about to purchase the electronics. Thanks in advance!

Thank you for sharing more details and for the CAD file! I will look at this for sure. NIce table that you made. I liked that too!

Also, I saw you have another one in green. How is this one different than that one apart from the spindle?

Ok nice work. Did you machine into the vice at the end ?
No, that sparks always occur when you mill the last millimeters, because the thin material cannot absorb the cutting heat.
Making a mill. First thing you need? oh just a mill and lathe. NBD.
Yes, that's a big deal if you don't have any machinery. But you don't have to own them. Ask a buddy or find someone to pay for.
Obrigado por compartilhar suas experiências, estou acompanhando seus vídeos e estava esperando por esse.

Great build💪💪💪 and thanks for sharing 😍😍😍 I will be going to built please share the BOM if possible... 🤝🤝🤝
Could you please post the links of servos in this build? Thanks. Great work btw. Not unusual for a german lol

I notice that your ball screws are single nut, do you have any backlash issues?
Yes, you're right. I'm concerning to swap to better anti-backlash nuts. This nuts have about 3-4/100 mm backlash.
You could try adding a second nut and apply pre- load. I did this with mine but I still have 0.04mm backlash.

Sehr gute Arbeit!! Mir gefällt der Ansatz eine CNC-Fräse aus Stahl zu bauen :-)

I am curious. What is the distance between the center of the two rails for X? Trying to figure out how much they need to be spaced apart.
You can get all dimensions using the cad file. The x rails are 180mm apart center to center.

1- which motor do you recommend, step motors or servo motor?

How's your progress?
Hi there , amazing work.
What software are you using ?
Thank you! I use LinuxCNC. It is free and very power full!
Hi, great work. Did you treat it with heat to relief stress in the steel contruction?
yes, all welded parts were heat treated

I like the spindle and can recommend it, however next time I would buy an atc spindle.
@@RUNCNC thank you for the quick reply. That’s great, I’ll have a look at them and add it to my list for comparison.
Very nice & solid machine, I really like your low profile vises. Can you share any information as to where they can be purchased?

Hi! XYZ axis is 750w servo motor?
They are 300W each!
bonjour impossible d ouvrir le fichier
Salut! Francais c est mal pour moi. Possible parler englais?
@@RUNCNC Sorry impossible to open file thank you
@@antopersempre1077 you need a prog to open step files. If you don't have one use free Fusion360 or use an online tool like sharecad.org
I uploaded it to autodesk: autode.sk/3UToSc1
@@RUNCNC it s ok thank you best regard
if you are doing it in steel, why not make your 5 axis machine like the DAISHIN SEIKI cnc mill that makes helmet in all youtube recommended videos?
5 axis? That's challenging! But I would prefer the hermle design.
