I did a horizontal calibration of 12 feet by 8 feet.
The exact conversion is 3657.6 by 2438.4 which won’t work.
( I couldn’t quite reach all of the anchors )
All anchor cables have to be extended fully ( let it stop at the full extension for each/all )
So add a few centimeters beyond the exact measurements so it doesn’t stop too soon.
I used 3680 x 2450 as the initial settings and extended all fully , then did calibration. 2024-05-30T07:00:00Z
My floor anchors were a 3/8" hilti anchor epoxied into the floor.
A 3/8" bolt,with a nylon washer above and below the maslow anchor suported by a spring to hold the cable above the concrete by an inch or 2.
you want to calibrate in the ‘known good’ area of your frame (the green zone as
shown by the utility at http://lang.hm/maslow/maslow4-frame.html ) calibrating
outside of that area introduces errors that will confuse the issue.
I’m confused by your comment that it “won’t work” and that you have to add a few centimeters to get it to extend fully…
My frame is something like 3658 by 2480. I entered that in the Setup/Config area for the frame size. I left the calibration size as 2000x1000 or whatever is the default.
When I Extend All, there is plenty of slack left in the belts to easily reach all the corners and have plenty of slack.
It feels like the same amount or more extra slack than I had last week using the ‘standard’ size frame. After the frame was embiggened and the frame size updated in Setup/Config, it extended enough more so that it could connect to the frame.
I’ve consistently also had the same issue where I wouldn’t be able to connect all belts if I used accurate frame dimensions and had to add a few 100-150 mm in either direction before calibrating.
When you “used accurate frame dimensions” do you mean that you had accurate dimensions for tlY, trX, trY, and brX in the config dialog or you entered accurate dimensions for frame size x and frame size y in the setup dialog or both? I wasn’t getting enough extension until I realized that my (tlY, trX, trY, and brX) were wrong.
I experienced something similar to this. I calibrated one day and by the time I was ready to cut something a new firmware had come out, so I updated and entered the values for my calibration into the t/b/r/l/X/Y variables without really thinking about them. I set the frame size and tried to extend all but it didn’t reach (by a lot in my case because I have a very large frame). When I took the time to look at and think about the calibration numbers I realized they were not reasonable for my frame size. So I reset them to something reasonable, extended all, recalibrated, and ended up with good numbers. I have no idea what happened in that first calibration, because the fitness value was really good.
When I gave it my frame size and extended the straps fully I was a couple of centimetres from the third and 4 th anchor pts
So I added a few centimetres to my initial frame size and then extended all fully and could reach all anchor pts before calibration
Trying to predict the thx tly values is derived from an assigned baseline
If your physical anchor pts are not orthogonal you won’t have the proper values
