i have a question about the settings to cut 1/2". Got my arc droid and a new titanium 65 set up and cut a couple of files and a pattern i traced out of 1/8’ plate and all went well but when i tried to cut a DXF out that i had created in Fusion (paid version as the free would not export to a DXF) in 1/2" plate in will not cut all the way through. i have the titanium at 65 amps and 110 psi of air. I set the tune to match a hypoderm chart i found on the internet. i have also moved the setting around in the tune section and have had no luck. Any help would be appreciated. i know i bought a cheaper plasma cutter but it is rated to cut up to 1 3/16" steel so i would think 1/2" would be doable.
Got any pictures of you set up? also do you have Fusion 360 Post Processor running, also how many volts 120 or 240 to your plasma cutter? Downloads – ArcDroid CNC
Good morning , i have attached the pictures of the piece i am trying to cut and the settings i ended up using to get one cut but it wasn’t pretty. I did verify i do have 240 v to the plasma. i was not running the fusion 360 post processor. i see it on the download page do i install it on the arc droid unit?
If I was doing this I would get a scrap piece and start punching out holes till my settings where just right. Next, I would wire brush overall and grind down to bare metal my ground clamp spot, always ground to the peace not the table, next I would increase my delay a bit and give myself about half the width of my lead in give your torch time to cut in before you start cutting my part last it’s just slag chip it off with a chisel before you grind down it down. Just a thought your air pressure may be a bit high it might be cooling the slag beforehand, also make sure you air is dry and check your pressure at the cutter a bad hose could be restricting your air (been there done that).
I see a few problems. All that rust is a issue. Clean up your material.
For settings I recommend,
.08” z cut height
.20” initial pierce height
.9 sec pierce delay
Feed 15”/min
I would also change the entry on you oval to the inside and about .250” of a lead.
Might be time to change your consumables….
And verify your Z heights. Do a dry run and stop during a cut portion. Measure the tip height from work piece. Comp your cut height setting to get what you actually need.
