In meinem RU-vid Kanal zeige ich euch nach und nach immer mal wieder Videos vom meinem Liebherr R944C Abbruchbagger der in 1/14 gebaut wird. Es gibt immer neue Videos wenn weitere Funktionen getestet werden. Sobald der Bagger fertig ist, folgen Videos von der Baustelle.
Viel Spaß bei ansehen und mitverfolgen!
Wenns euch gefällt lasst ein Like, Kommentar oder Abo da ;-)
My youtube channel gives you the possibility to follow the proccess of me building my Liebherr R944C demolition excavator in 1/14. I´ll always post new videos when I test further functions. As soon as the excavator is finished there will be posts of it working on construction sites.
Have fun watching and following the progress!

I have also have to hook up JMC servo. They should be really good. Did you connect the alarm signal back to the BOB? if yes how did you do it? Reading different opinions about it. What setting are you running for constant velocity? From the movements looks like you are either running it not in CV mode or with settings to exclude it at a certain angle and distance. Thanks a lot!
@@andirchydraulik1191 OK thanks for the infos :-) Then the CV mode must have angle limit setting becuase you can clearly see that it's not doing CV when there are right corners. I am also running like this I was just curious what settings you use for it.
@@andirchydraulik1191 yes that's what I thought. 30 degree is really a lot that's why it looks basically no CV. Usually is common to set it to 89 degree. So only above 89 degree will avoid using CV. You are basically running in exact stop mode since everything above 30 degree turns off CV. For the distance I usually don't use it. I found that you want to set the motor acceleration as fast as you can, that reduces the slow down and speed up time needed for the CV and exact stop.
Have you tested the accuracy of the servos? I'm interested in the JMC servos to make the control cabinet smaller and cleaner, I just don't know what sort of resolution the encoders have and how accurate they would be with a 10mm pitch screw. Nice work!
the servos are 1000 line, so low resolution, but can easily run 2000/4000 steps (or more tho you get problems there with step signal frequency with a lot of boards) per rotation. The torque is also fairly good (imgur.com/a/RcnsXrW quick test on a dovetail machine, which has insanely high friction and a 40kg table). I would not compare em with with steppers as they leave em in the dust (do watch out for Z axis tho, as on power loss they have no holding torque unlike steppers which have detent torque, so the Z axis will drop if you remove power, so you need a Z brake). All in all for the price they can not be beaten. The next upgrade motors from JMC are round 170$ vs the 78$ which the 180w IHSV servos go for (the 400w IHSV are 100$ and still make sense if you use a Cisco Catalyst 6500 PSU, otherwise you can just go directly to the 220v motors). Mind you the 170$ motors are much better (17 bit absolute encoder, so round 131k positions) as well as more powerful since 400W.
RC Menzinger Agrar&Bau Danke! Ja das ist eine Rigipsplatte. Mörtel geht aber besser da es einfach besser bricht... Rigips drückt man zusammen und die Pappe hält es dann noch zusammen.
Hondo, ich verfolge die Herstellung Ihres Bulldozers. Sehr zeigen. Ich habe vor, auch einen zu machen, aber ich brauche Ratschläge und Tipps von jemandem, der Wissen wie Sie hat. Wenn Sie mir helfen können, könnten wir E-Mails austauschen? Hättest du die Spezifikation des Planetengetriebes, das du beim Dreh benutzt hast? Haben Sie es auf einer Website? Die Rohre verwendet, um die Zylinder zu füttern, verwendet Sie 5/32 mit Wand 0,5? Ich frage, warum ich die Teile und Materialien kaufe, um meine zu starten.
