I still struggle to get the home position right on my Sainsmart 3018ProVer. I think this is also linked to my previous issue. https://forum.lightburnsoftware.com/t/recently-my-3018-prover-behaves-a-bit-odd/81080/5
Strting from zero I run my initialization string:
$10=2
$30=100
$32=1
$110=1000
$111=1000
$120=3000
$121=3000
$122=3000
G10 L2 P1 X-262 Y-315
$H
This should put the laserhead in the bottom left corner and call that (0,0) - my understanding at least…
As my material is on (x45,Y10) I use goto position to get here.
Before that I used the “?” on the console to check the current position:
?
<Idle|MPos:0.000,0.000,0.000|Bf:15,127|FS:0,0|WCO:-253.000,-316.000,0.000>
ok
Starting stream
$J=G21 G90 X45 Y10 F1000

ALARM:1
Hard limit triggered. Machine position is likely lost due to sudden and immediate halt. Re-homing is highly recommended.

I can joggle along to x45, y10 with the arrows but some how the laser started out of position, which destroyed the work…
Also after homing and running the initialisation string, the current position on the move screen isn’t always 0,0…
Where do I go wrong?
Thx.
