Hi Juha,
I bought a liteplacer full kit about one year ago.
Until today everything is ok but I like to use new mount camera design beacause I think is better for adjust position.
Can you share STL file for printing? Thank you.

New camera mount design
Re: New camera mount design
Sure! Please give me a few days to get back to my office.
Re: New camera mount design
News here? (I absolutely don't want to bother you I'd just like to reassemble the machine)
Thank you
Thank you
Re: New camera mount design
Sorry, I was sick for a few days an didn't get to my office. Anyway:
You can find pictures and usage instructions on assembly instructions. Maybe I'll get into writing a blog post about the new construction, but don't hold your breath on that... The new downmount is better than the old as it can be locked in place, where the old mount assumed that the mount doesn't move on spring tensioned screws. Also, you had to be careful not to cause camera module movement via the cable: when the machine moves, the cable twists also, and you have to secure the cable so that the camera module doesn't see twisting forces. There is no new benefit for the uplooking mount, just dimension changes.
The downside is that the new camera module is bigger, so the mount is bigger also. If you convert an existing machine for the new mount, you need to adjust the X max limit switch and machine size for that. Also, as the dimensions are different, you need to re-adjust camera offset and since the camera Z height changes, also the pixel size. Finally, the camera position in the machine has changed, so the camera doesn't see an existing homing mark on a new mount. To fix, you need to adjust yzb parameter (Y Zero Backoff, the amount the machine moves away from the latch after homing Y). To change, send text "yzb=24" (without quotes). The 24 might not be suitable for you, that is what I use. If not, adjust.

The new 4k camera module is bigger than the old 720p module. If you want to use the new mount with the old cameras, the stl files are not usable, the Fusion 360 design files are much more beneficial. They are here:

If you do modify the new down looking camera mount for the older 720 camera module, please share!
Some design notes, downlooking:
The left-right cradle part has round "mickey mouse" tabs at the end of long narrow side walls. These are only for keeping the long strip attached to the bed when printing the first layer; cut off before use. You need some additional hardware: M2 5mm screws, M2 nuts, 6mm M3 screws and nuts. Also, you need some small self tapping screws with nylon washers. For these, you might need to experiment on the hole size: You want easy but solid attachment to your print but not break the plastic. The exact hole size is likely filament and temperature depending. The screw I use is Farnell/Element14 part 2474937 and washer is 2472664.
The mount to the machine needs very low head M5 screws. I use Misumi CSPSLH-ST3B-M5-10.
Sales pitch:
I have the new 4k camera update in my store now.

Re: New camera mount design
Hi Juha,
I am very sorry that you have been sick. Hope everything is ok now.
I don't have specific skills in technical drawing so I don't think I can modify the drawing. Maybe I'll try.
If I can, I will surely share it. Damn I thought it was also compatible with the old model of cameras that I have.
No problem I will replace the old support and as soon as I can I will buy the new kit. Thanks for the valuable tips and files.

Re: New camera mount design
Forgot to mention: If you (or someone else) gives this a try, you can grab the CAD model of the old camera here: http://a360.co/2Dw8c3k
Re: New camera mount design
Doh. I also forgot to add the link to the new camera model. It is HBVCAM-4K1928 from Huiber (https://www.hbvcamera.com/). On Alibaba: https://www.alibaba.com/product-detail/ ... 67807.html
