Obrigado, isso me deixa muito feliz. Infelizmente não falo português e tenho que usar o tradutor do google. Acho que terei mais tempo para vídeos em breve. Saudações Markus
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!
- 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.
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.

hi, I wonder you only use 180 W servo motors? I'm about to use 750 W servo for a metal milling gantry similar to what you have already built. I was afraid 750 W would not be enough power in order to move such a rigid and heavy gantry. (movable gantry, something like your size but movable) Now that you have it up and running, ... no trouble at all regarding power , quality of work? As a whole, you have done a great job in my opinion. I would like to here, read from you. I can tell you are an advanced, skilled cnc-er. thank you .
No need for more power here. The moveable y is the heaviest part with about 80 kg. On a 5mm pitch ballscrew this is a piece of cake for the servo. Thank you for your kind words! Well this is my third attempt building a router. You increase your skills on every build.
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.
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!
@@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
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 …
