Gave mine a decent test last night in very warm conditions, average RMS between .5 and .9 as the atmosphere was very wavy. Stars looked great. Only issue was when it went home end of session it was at 90 degrees west instead of up despite having set it at the start of the night and tested i to go home more than three times. Have to investigate further. Also have to check and see if meridian flip worked. ASIAIR was used.
Edit: Meridian flip worked perfectly, now to sort out the Home issue.
Garymck thanks for the link to switch off tracking at start. I have just done mine. Looks like the board has been updated. Mine did not have plug that goes to the brake. It must hsve been spliced into the power lead. My stepper drivers are plug in so would be easy to change for faster ones but we would need the source code to change the setting in the firmware.
mine has the same board as you including socketed stepper drivers. and no seperate lead for the ra brake. The drivers are TMC2209's so won't need to be changed. I also fitted small heatsinks to the drivers "just in case".
I was happy using it with the asiair, but after the firmware upgrade on the mount to stop it tracking on startup it will now not slew on the asiair despite it working as normal on my laptop using the ascom platform. IS anyone else using an asiair and have upgraded the firmware and now can't slew the mount?
Update, I started everything again this evening and it all works. I did nothing to it go figure, it may have been a glitch in the matrix or fiddling with the settings when I had it in Ascom.

What tripod I should get that will fit Juwei-17 baseplate?
I just ordered the mount and need tripod. I'm fresh new to all of this so I have nothing yet except Sky-Watcher EvoStar 120ED that will arrive tomorrow
Thanks!

Depends how lightweight/portable of a setup you need
If weight is not an issue, I'd recommend a steel tripod like the SkyWatcher NEQ5 with an adapter
If you need portable (ie carbon fiber):
- Cheap option is a Bexin ST402C
- More expensive option, but worthwhile in my opinion, is an Innorel RT90C or its variants - (Amazon is cheapest currently)
- You would need to 3D print some parts (plate adapter and tripod spreader)
- If you don't have access to a 3D printer or don't want to fuss with it just get a ZWO TC40
Thanks a lot! ARTCISE AS90C looks like the winner!
I ordered smaller brother of RT90C, INNOREL NT404C, also 40mm tube, 30kg load, but mounting plate is not ideal, can be a challenge ... $280 on Amazon AU.

I found Innorel RT90C on eBay AU for $382, only 2 left.
NT404C goes back to Amazon
I do have 3D printer, Bambu A1 Mini, sweet thing. But I'll try to make aluminium backing plate, I think plastic filament is not solid enough. This is the point of max torque ...

Thanks jurkob!
I mated RT90C to ZWO PE200 pier. Ready for Juwei :)
The black insert piece under three bolts and spreader are 3D printed. I modified it a little, holes are now 66mm all the way through. Ask me for STL file.
Bolts are from Bunnings, M6x30mm stainless steel. Center bolt M8x120mm, I had to file off a little from sides of the bolt head to fit it into the plate center hole.
Btw, if anyone wants unmodified insert, for shorter cup-head bolts, I can send it for free, just cover the postage.
I've got it's younger brother, the J14 coming soon. CNY so it'll probably be a couple weeks.
Already have 2 x AM5s so this is one for a new rig. Didn't want to spend the $$ on a AM3 and picked this up for $1,290 + $140 shipping. Lets see if I get hit by GST or not.. still just over half of a AM3!
Its got a 8kg/13kg load limit which is the same as the AM3. I'll probably not be north of 5kg anyway.
The absence of the homing feature is a bummer (feels like a software issue?) but not an issue for me since Im going to be using this out in the field when Im next to it.
Just spent 2 nights at the ASV's Heathcote sight. All worked perfectly. Best guiding was .5"rms, had some terrible seeing and guiding did get up well above 1"rms, but that was not the mounts fault, just despite being clear, the wind was strong and gusty. Found best guiding performance was with short .5 sec exposures with low aggression on both axis (60%). When the wind died down, guiding wa typically .5-.8" rms.
Very happy with the mount - carrying an SVBony 122mm f7 with no counterweight.
