Yeah right....

Go for the ubiquitous die cast case, i.e. https://www.ebay.co.uk/itm/Waterproof-enclosure-Instrument-Aluminium-diecast-electronics-project-box/153525629026 easily drillable \ paintable, can even be machined.....

Go for the Prusa, it will just work & produce very good results..... but then I'm biased, as I have a MK2s, as well as others, but the Prusa is always my go to printer, unless what I want printed is too big.

Depending on size & complexity, I sometimes 3D print them as well as using 2\3mm plastic sheets....

You can pick up 2nd hand Synology storage bays on eBay, then just buy new disks to go inside..... That's how I built my 12TB system, for a lot less than the SCAN price.

Better still, buy a Network Storage device e.g. Synology \ MyCloud etc. as these tend to be more robust and have built in backup routines etc.

Do any updates now, manually, before it does them automatically. Even for 1903 there are a few large updates to be applied....

If you are plate solving, does it matter ?? as any discrepancy in location will be ironed out....

I've managed to sort out my issues with the latest version i.e., finger trouble & board not taking defaults unless extra settings are viewed, but as you are using a DRV8825, beware trying to drive the motors too fast as that particular driver may require fly-back diodes to smooth out the current flow.

Only use the updated code for testing, as I've found what may be a flaw in the code with regard to step range..... and there's an issue with a library definition name.

How have you set the current on the DRV8825 daughter board ??

I doubt that they would be at fault, but no harm in looking, BUT BE VERY CAREFULL, the connectors are small and surface mounted, so can VERY EASILY be ripped off the motherboard.... I know, because I've done it !!

This is what I mean : And for completeness, the full drive controller (Note that the PCB layout is my own design, using Robert Browns circuit):

to connect to the motors, I just use standard RJ11 4 way connectors \ standard flat telephone cable, never had any issues....

If that's the case, then check your cables\connections, it may well be a 'dirty' connection where PHD2 is issuing a nudge, but the mount isn't getting it. Also check the guiding algorithms aren't too aggressive.

That screenshot shows that the PC is expecting to contact a local server for a downloadable installation image, which I'm thinking that you don't have ??

For my ED 80, I printed the motor housing (Nema 17 PG27), which just bolts onto the end of the focuser, replacing the 'normal' knob...

How about the Debug logs in Documents\PHD2 ?

What do the PHD logs show ?

These things are sent to try us...… but better to find out now before bad weather sets in & you want to close it quickly.

Modded Canon, I use a 600D with either Samyang 500 mirror lens or Vivitar 28mm widefield.... I piggy-back it on top of my main imaging rig, & take secondary pics while the main rig does its thing....

Yep, that sounds like the 'expected' backlash... You need to adjust the motors to worm-wheels slack, then the worm-wheels to axis engagements..... There are some YouTube videos showing you how to do this....

Its ALWAYS a bad move to run everything as Administrator, outside of testing, as it will introduce other errors, some of which may not be noticeable.... As all the software we use, has been written with standard user privileges in mind, therefore check your user account has full access to all the software, and that no application security permissions have been amended.

And another miscreant scope gets a makeover …. wonderful !!

What is slack on the motor ? there is usually slack\backlash in the meshing of the gears being driven by the motor, so the better place to start would be to perform an adjustment routine, to reduce any slack\backlash in the system.... This is preferable before changing the motors.... although I've not tried it, it may also be possible to upgrade to a belt driven system, which will also 'clean-up' the drive system.
