Dear Members

Background
I'm using an Orion Delta which is NOT connected to a PC, all the printing is done via SDCARD.

I'm looking to adjust the 'Horizontal Radius'.

Page 31; paragraph 13a) of my version 3.05 Orion Delta Printer Manual suggests I look for Horizontal Radius in my host software. (extract below)

Question 1, Could this 'host software' in my case be 'MatterHackers:MatterControl 1.6'?

If yes

Question 2, As [OPTIONS] [Hardware] [EEProm] [Configure] is greyed out in my MatterControl; is there a way to update the 'Horizontal Radius' via SDCARD?

Observation; It appears that my 'Horizontal Radius' is about 0.1mm lower than the centre.

Question 3, Is this '0.1mm low' excessive or am I overreacting?

Any observations or thoughts on this matter will be much appreciated.
Sincerely and in good faith

Extract
13a) If from the center gap, the nozzle goes DOWN toward the glass at ALL 3 TOWERS, load your host software and bring up the EEPROM information. You will look for Horizontal Radius. You want to RAISE that number. I suggest raising it by 0.2 and run towers.gcode to see the change, and keep raising the number till the gap evens out (changing this number will not make you need to re-set your z height, it will just raise the outer edges where the nozzle pauses).

Hi,

Avoid software leveling, such as within MatterControl. Level the machine itself.

The following wizard works very well. Just follow the instructions.

Dear PartDaddy

Thank you for your prompt reply.

I read the Delta Calibration Wizard page while doing the research before posting my cry for help. Unfortunately I / we don't have an 'HE280 accelerometer probe to detect and identify deviations and calculate the corrections needed'.

When I followed the instructions in the Orion manual Page 31; up to paragraph 13a I'm reasonably sure that (if the manual is correct) the deviation and correction needed are 0.1mm around the 'horizontal radius'

Is my understanding of your reply correct that I should not use these instructions in the manual?

And finally is 0.1mm low around the horizontal radius excessive, or am I worrying over nothing?

Yours sincerely and in good faith
Martin

0.1mm is pretty darn good actually. Try some test prints and see how it goes.
