Hello wise board of SMA! I am planing to make simple moco unit with Arduino system. I got great help from previous post about the subject and from Simon Tytherleighs comments.Things have developped…Continue

"Looks great. You could consider using a Fotomate sliding mount for the camera. Also, my sense is that the base should be as wide as possible for stability, but I know the commercial units limit this. Well done! Now for the tests. Try repeating a…"

"I got my moco running! The rail is Neewer and was supprisingly good for 60£. For board I got Mega 2560  with RAMPS 1.4 Controller with 5 A4988 Stepper Motor Drivers. I had to adjust the DFmoco code a bit to get it work with Ramps 1.4. But…"

"Those shoes are impressive!  I get acceptable results by sculpting shoes in plasticine and slush casting with liquid latex, but those are a whole other level. "

"Glad to be of help. Good luck! It is quite a challenge, but very satisfying once you get it going. Expect to have to modify things a little to improve them as you go. I look forward to seeing your progress. Go Tatu!"

"Thank you Simon for all good info! I really appreciate it. It is long process to figure all things out from scratch. I think that I am ready to order the parts now. I will post some results when i get so far."

"If you use geared steppers there will be some backlash. The ordinary geared steppers seem to vary in their backlash quite a lot, and I found them unacceptable. The high precision ones are made much better, and their backlash is much…"

Tatu P replied to Tatu P's discussion Bearings for moco camera head
"I hope that system could be usable. One thing is motors backlash. 30:1 gears has Backlash at No-load: <=25 arcmin -  which would mean 7 hole steps! With this accuraty bigger gear would be pointles? And is there any use of microstepping? Are…"

Simon Tytherleigh replied to Tatu P's discussion Bearings for moco camera head
"This is all sounding pretty good. Just make it as accurately as possible. For the stepper motors, I have found that the slower gearboxes, 30:1 and up are what is needed to slow things down. When you think about it the pan and tilt will not be…"

"I think that I will go for one thrust bearing and put pillow bearing as top part (maybe this). Then I have bearings for both surfaces (vertical & horisontal). 10 mm rod should be steady enought. The thrust bearings width is 3 cm witch will be…"

Simon Tytherleigh replied to Tatu P's discussion Bearings for moco camera head
"I think this is where your thrust bearing comes in, although it would not be necessary if you use similar bearings to mine, which are wide and stable. You want to avoid friction, or you get 'stick-tion' where something does not move when…"

Tatu P replied to Tatu P's discussion Bearings for moco camera head
"Pan bearing can be weak point. I have to tight the shaft so that pan axis is steady, but same time there will be more pressure for bearings. Propably pressure will cause more friction. That + shafts friction will make connection a bit stiff I…"
