Okay, time for me to pay a bit of my debt forward.

1) Stepper motors have a sweet spot on Voltage. In reality it is a sweet band of voltage that will allow it to operate at it's highest speeds...

From the original post you made the statement that 5mm pitch will give you slow rapids. What Voltage do you plan on running this at? As mine is running on slightly more than 60V and is capable of...

Yeah measuring the filament is something that gets done on all incoming spools as they vary. SLA/DLP is getting down in price point but I am waiting for SLA1 as they have been doing a lot of work to...

Hello Folks,

I have been running two MK2S Prusa's for over a year now and they are now upgraded to the MK2.5S. The expense is worth it in my view and will be buying some MK3S's shortly for...

Depth that you place the object at is in the toolpath control section. best bet is go watch the Aspire videos as they do a very good job of explaining it. If you don't get a good grasp of it there, I...

I know the feeling. Best wishes. Yes, I still live and breath though it has been a good bit close a few times these last years. You deserve to enjoy the fruit of a huge amount of labor. So get to it...

Okay,

First question is this machine Hobby, Semi-Hobby (you are going to be making your own commercial items on it, but not full time business), Semi-Business (it needs to earn it's way and might...

What are you milling mostly? If milling metal alot you might want to look at the 3kw spindle even though it does not give you a bigger ER collet (cheap buggers a ER25 would be so much more useful) it...

Do you have a drawing of what the draw front looks like? I might know a few folks that can help or be able to get new ones made to fit the job (or a slightly different design that still fits the...

JAZZ is completely correct there. What takes time and really makes code generation easy is setting up your CAM program properly and making sure the post processor is set up for best practices on the...

Have seen them running and did ergonomic function evaluation on some of the older models 7yrs ago. They look nice and did the job very for the company I was working with at the time. Looks like they...

If I understand the drawing correctly, you are looking at this being 2m by 800mm in overall dimensions. That might be a little wide for a single central ballscrew, as racking of the gantry can start...

Adding to some good points already given,

1) rotate your rails so that they are opposing each other (one facing up and one down) That will bring your Z plate closer to Y as well as be a better...
