HELP for mac and Delta rostock mini g2

[delta]

Sorry. hope im in the right section. please feel free to move my post.

Hi. I just purchased a second had rostock delta mini g2. the owner used it for a month and sold it to me. I know the printer is good because when i purchased the printer, he printed something on it and it looked good. REALLY GOOD.

anyway, he was using a windows 10 OS for his printer, i have a mac..

and i don't see a lot of documentation on how to level, calibrate manually etc for a mac. i managed to connect the printer to my mac and was able to print cubes and cylinders. and they don't look good at all.

first question. how do you manually calibrate (without the probe) how do you make the printer head go to the three outer points so that i can check if it's leveled coz i don't have a similar window in repetier host for mac?

2nd. im getting prints like this. what am i doing wrong with these? my print head is 215 and my bed is 70. am using Esun PLA. i think my print speed is too fast. where do i change that?

i really hope someone can help me. i need this to work thanks

I think you need to manually enter the commands here:

Thanks @ mark. i finally figured it out. there was something wrong with my settings at slicer.. the link helped a lot. question tho. im afraid i might burn the hot end soon. does this hot end perform good or what hot end performs the best?

also, what other stuff might break down with my rostock? i would like to stockpile on parts incase im doing something and something breaks down.. belt, motor, etc.. what would be best to stock for "safety parts"

thanks

HI. also. how long do you use your printer? will 5 hours on a single job be bad for it? would it fry anything?

this j-head is for the I3 seires, your printer is G2, so you'll need the long distance one.
As for the safety parts, is your printer has those printed plastic parts? If not, then don't need too much spare parts, maybe stepper drivers, the metal parts of my G2S are so far so good.
" will 5 hours on a single job be bad for it?"
I usually print parts last for about 7 hours, so I think it's fine for it.
