I was thinking of remotely closing my roll off roof with SGPro . I was wondering does anyone do this now and what electronics board would I use and software to make it operate and possible contactors or relays would I need . I have a cable system that pulls open and pulls closed the roof. I was looking at garage door openers but I cant find one that will open a 20 ft run , everything is a 8 to 10 ft run on garage door openers . I basically go out and open roof and turn computer on and scope and come back in house and remote control by inside computer and I was wanting to, after end of imaging the scope parks and the roof would close this is what I would like .
Here at the Stellar Skies dark sky site operation, most of our remote imagers open and close their roll off roof observatories using the motor system sold by Jim Collins known as the MVO Control system. You will need to convert you observatory from a pulley system to a rack and pinion system with the supporting automation. While not cheap ($2K), it has proven very reliable and Jim provides excellent customer support.
MVO is OK but as with most of these it is spendy. I did mine with a rack and pinion system (you can buy the rack and pinion gears from McMaster Carr). The control board is a single Maxdome board (you only need one for a roll-off instead of two as you would for a dome). The drive is a 240 volt 3 phase gear motor running from a 120 V single phase to 240 V three phase frequency drive converter. That has the huge advantage of not only being able to dial in the desired roof opening speed but also to be able to ramp the start and stop as you wish. This results in very smooth and quiet operation and way more power than I need for my roof. If you have access the the ACP forum, many details were discussed there on this thread - it is way too detailed to describe here.
Be aware that some of the parts I used may not be available anymore as that specific part number - there are probably equivalents. One thing to be aware of with R and P systems is that although they are very smooth, they can “rack” a poorly or lightly built building.
My own observatory’s roof is controlled by a servo motor system I built myself. I am only aware of Jim’s system from what other members of Stellar Skies have told me. Jim’s system has a lot of configuration options and it is likely that one of those options is preventing the roof from closing automatically. As mentioned, Jim is very helpful to owners of his system so contacting him will be your best option.
