I'm new to working with a lathe. I have ordered a Harbor Freight 7x10 mini lathe to do some work on wood rods.
I've been looking at cutter tools but am wondering where can I purchase cutter tools...
Thanks for those links. I did verify that the Harbor Freight 7x10 lathe does have an auto-feed to do threads. I'll probably end up getting one. Thanks.
I am looking at a 7x10 mini lathe. I was unsure of how you actually cut the threads, but the Beall video made it clear it's a manual job unless your lathe has an auto-feed feature. Probably the...
I'd like to be able to cut the threads on my own lathe vs having to buy another specialized thread cutting kit. The video did answer my question: hand feeding and turn the rod looks like a hit or...
I'm new to lathes but have a need to do work on about 5/8 inch dia wood rods. I will need to be able to cut threads at the end of the rod. Never having done this before, should I be looking at a...
I'm using a LaserBot/MegaPi laser machine. Does the Marlin firmware have a 'laser mode' or g-code word that doesn’t stop the laser head when we switch the beam on and off during movement?

Hi Greg,
A lot has happened in the past 18 months since I first posted in this thread. Let me bring everyone up to date:
1. Benbox Laser Machines/CO2 Lasers/3D Printers - Index is a community...
I downloaded Marlin firmware version 1.1.0 RC 8 and flashed this to my laserBot laser machine which has a MegaPi controller board. The laserBot is now working fine.
I have a 3D printer frame...
@RCaffin you're correct...that fixed it...thanks...
I am the developer of BenCutLaser, a new CAM software application, for all laser machines, but specifically developed for low powered laser machines (5.5 watts and under) and the problems they have...
Solved! The problem turned out to be precision. I was using 2 place precision in my gcode and when I went to 3 places, it worked. I don't quite understand why that made a difference but it did.
I've got a small laser machine, with a 2.5 watt laser diode. I'm trying to cut 3mm wood and from testing small square cuts, I know it takes 7 passes to cut cleanly through the wood.
The problem is...
I've been hand coding Circles and Arcs for awhile. I've come across an Arc that gives me an error and I can't figure out why.
I've manually debugged this Arc on a paper graph and the G02 line...
I'm writing gcode to follow a Spline/Curve along a path of X,Y points.
I notice however, that when I send the gcode to my laser machine, the laser head moves in a jerky fashion vs smoothly.
Is...
This is the method I chose to do. Thanks.
Thanks for taking the time to explain this.
I'm doing this at the hobby level so I have a very basic laser machine...and its using Grbl and therefore doesn't support variables or macro's.
I...
From what I can find online, it looks like I can make an Ellipse and an Elliptical Arc by making individual Arcs...4 Arcs for an Ellipse and 1, 2 or 3 Arcs for an E-Arc...does that sound right?
I'm learning to gcode manually my laser machines.
I've spent the last month working with circles and arcs G02/G03.
Now I'm starting on Elllipses and Elliptical Arcs.
Is there a G02/G03 like...
Thank you...!!!
I was looking for a formula to calculate Arcs and came across this reference: How to program arcs and linear movement in G-Code manually - All
I've been doing manual Arc calculations and writing...
I confirmed with the Grbl folks that G40, G41 and G42 have not been implemented. They indicated this would probably not be added in the near future as they have more important Gcode to add to their...
Rats...G41 isn't supported in Grbl 0.9i and I thought I had read that it was.
I get an error: unsupported command at that G41 line:
G91
G21
G41 P0.50
G01 X0 Y0 F2200
M03 S76
G01 X+00 Y+10...
Thank you for the detailed answer...I will give that a try with my Grbl ver 0.9i.
I'm writing my own gcode actually and sending it to my laser using Universal Gcode Sender. I will look into the radius/tool compensation gcode command.
Thanks...
I'm using the latest Grbl ver 0.9i and I am making 10mm square cuts through 3mm plywood.
Am I able to execute a gcode command that will allow my cuts to compensate for my laser beam width of 0.5mm...
Thanks everyone...!!!
I guess I'm mixed up here. I'm moving my laser head to a position that I want to set as my new 0,0,0 reference point.
So I jog (using G1 X Y code) to the position I want and then issue G92 X0 Y0...
Yeah it's something to do with your connection...folks are posting there today and I am posting there too...sorry for the troubles...
No, it's been up...I've been on it posting and answering threads: Benbox Laser DIY Machines - Index
