The bracket for the SV04 install on the laser, itself, doesn’t seem to line up. I can use one screw, but not a second one. Did I get the correct bracket? The mounting brackets broke - Would an STL of both parts of the bracket be available and I can reprint these parts?
If I understand the video correctly, the power connector can be inserted in KFAN1 or KFAN2. I am hoping to leave the fan for the extruder plugged into KFAN1 and keep the laser power cable plugged into KFAN2 all the time - even when 3D printing, but M106 seems to only power KFAN1. Might there be another M code to power KFAN2?
Hi,
I know this thread is kind of old, but have you resolved this issue? Trying to get my laser working as well.
My holder broke, too. created my own STL to replace it.
Hey there,
I also created a replacement holder and started modifying a post processor to produce the gcode which works, but need to back on it. Maybe this will be my next project…
I got my laser to work when I connected it to K-FAN1 on the board for the left extruder. It stays off when connected to K-FAN2. I assumed, but was obviously wrong, that K-FAN1 and 2 connectors are on the same circuit…
It took me a couple of tries to find a setting that doesn’t totally char the wood when it’s supposed to only engrave. Will need to continue experimenting to find the right speed and duty cycle settings for engraving. Even a 2% duty cycle makes a pretty powerful laser beam, it seems. I did not expect that.
By the way, I am using the laserweb software under Ubuntu to create the gcode.
I am new to all of this. What’s that post processor thing for?
I will have to look into laserweb. I am still working with SheetCAM as I already have a license for it and it can work with custom post processors which basically writes the gcode for the intended machine. Right now, I can rewrite the X and Y origin so I can offset the laser mount distance to better match the printer bed’s position.
I haven’t went much further at the moment other than cutting out a few rabbit silhouttes
I’m still playing with speeds depending on material and material thickness.
