Re: Features for a motorized stage (focus stacking)
... there's no reason to buy Thorlabs' motorised rails. They require coding, they require an expensive K-cube controller ($800 I think) and the power supply is also $300, you need a controller/interface that goes beyond "move rail to POS A", you code your own. Want the controller to also take pictu...

Re: Features for a motorized stage (focus stacking)
this is one of the most helpful forums I've ever encountered, if you have the feeling people don't want to help you or are being rude then I suspect you're doing something wrong. chris, Are you neglecting lothman’s behaviour in this topic by referring to a forums course of events? That this is a he...

Re: Features for a motorized stage (focus stacking)
lothman,
you can’t bear criticism, acting rude by (keep) speculating, generalizing.
our communication tells about both of us.

Re: Features for a motorized stage (focus stacking)
Rik, Thanks. I meant motorized stage, instead of motor. I want (as a hobbyist) to compare and choose (the values for parameters from) motorized stages which are under/best/over dimensioned for (a) certain focus stacking task(s)/application(s). Motorized stages like e.g.: - https://cognisys-inc.com/f...

Re: Features for a motorized stage (focus stacking)
lothman,
I agree that we disagree.
You did not give values, don’t know values for the StackShot.
The answer on your speculations are in my other topics.

Re: Features for a motorized stage (focus stacking)
elf,
I ask for values.
You try to impose your opinion, did not give values, don’t know values

Re: Features for a motorized stage (focus stacking)
I am not aware of any studies for most of your parameters. In that quite long list, the only value that I have ever cared much about is "min achievable incremental movement". See https://www.photomacrography.net/forum/viewtopic.php?t=16323 for a study of that, using one of the earliest StackShot co...

Re: Features for a motorized stage (focus stacking)
Hi elf,
Can you explain, why should I first define my tolerances for each of those fields for the StackShot, before that someone mention the values for those fields for the Stackshot?

Features for a motorized stage (focus stacking)
Hi, I read that features for a motorized stage are e.q. travel range, velocity (max, min). acceleration (max, min, at a load), resolution, bidirectional repeatability, flatness and straightness over full travel range, horizontal and vertical load capacity (max), min achievable incremental movement, ...

Hi Scarodactyl,Scarodactyl wrote: ↑Wed Aug 05, 2020 8:03 amI think Scienscope sells a much cheaper domd illuminator. That might at least serve as a starting point.

Re: Q: (dome, sheet, tilted) lighting for DSLR+tube lens+plan APO
Hi Ichty,
Thats a lot of money for the lighting dome.
Thanks for explaining. Assumption: for a dslr+tube lens+plan apo setup it must be possible to move a plan apo (before or during stacking) into a lighting dome, due to working distance. Correct?
