Take my advice, that's not a setup one want in a high end machine.
The pump itself, HR7, is top notch, used by Premacon and others, but with Magoms setup there are taken some 'short cuts', in order to keep the price that low.
Better take a look at Premacon's setup with the HR7, 900ml. They got the motor and planetary gear-drive as it should be. An issue is size. Your machine is quite compact. most ideally would possible be the 750ml Damitz pump?

OK great I will take your advice. I'll post more when I dig into it and see what I have.

Honestly it looks like the boom and arm are moving plenty fast already. Which makes me think you already have the bigger pump and the issue is somewhere else?

Whats your current status? A (german based) community is also in regular exchange on facebook, so you could subscribe and try to get some help through this channel as well.

Another option is to call damitz directly...

hey first off thanks for messaging and helping.

current status = I unplugged track servos so I don't accidentally open valves. I don't dare attempt to take this thing apart. It's too advanced and nice for a hack like me to touch. I have no clue why #1. the tracks were so slow because the pump handles all the other functions just fine. Speed on cylinders is good and swinging and lifting at the same time is not an issue. #2. why SOMETHING broke and the tracks don't move and it just dumps oil when a track valve is opened.

I am trying to get a hold of diggingwithmartin and see if he can help. He is only about 3 hours drive from me and he has done work for others before. As of right now that is my plan.

anyone wanna buy this thing?? hahaha
