average hours per day must be near 12 per day, however latterly it has been on 16 hours or so every day for about 2 months..

my idler pulley went recently, and I had lots of layer shifting, printed a new set...problem gone.

upgraded to an M3 rod...quality was vastly increased, cant over emphasis how much that one change made to the machine...

sure I level the bed,,,maybe once every 30 hours or so?

new filament spools have a tendancy to slip off the spool... i need to design a small clip to prevent this....

warping is my biggest bug , however, printing with a 5mm brim helps.. but allowing the print to complete the first layer then using acetone on the brim helps to hold it down and 'minimise' warping as much as I can...

really, I can't fault it for the money, hence the reason to buy another one this morning

I need a new one for a job for a client and I know this machine quite well now, so it made me go for another

couldn't be bothered with learning a new set of probs with a different printer...

both for me...

I work as a design/draftsman, my own company etc.... so use it for prototyping and modelmaking.

personally; it's used for the inmoov robot

currently have an SD2 - New SD3 arrives tomorrow (need the bigger bed for a current job ) time to get that lead screw swapped out !

how often would you say you use on average and how do you find the reliability?

But I regularly have to level the print bed, tweak slic3r settings, have gone through 4 hot ends in 6 months on 2 machines, had to replace 2 print heads, a fan, and often it takes 4 or 5 attempts to print a part.

Often, it's a case of print as much as possible whilst its printing well. Even then it's only a few days, a week tops, before it needs adjustment/repair.

I can print loads one day, then the next morning go to print and it needs recalibrating again even though nothing has changed.

As well as the mentioned repairs/mods, I have also added insulated covers, and 5mm thick mirror glass beds.

Is it just for personal use? or do you use it in a professionally?

I run a small Industrial Design Consultancy, and use my SD3 for prototyping parts. However, for daily use I find it (especially unmodified) rather unreliable.

Are there any professional or personal users that use it regularly (daily) and are getting reliable and consistent results?
