BenCutLaser / Re: BCL 1.8.5c Beta Release (INFO)
« on: Today at 08:31:37 PM »
Here is how the G04 P5 (Pause) command is shaping up. I've got it almost done and I'm working on the last part: adding it in the right spot in the g-code for the various drawing objects (Lines, Polylines, etc.).

There is a setting in the ini file: G04 P in case you need to change it. The seconds value comes from the drop down list and mates with the first part of the g-code word to form: G04 P and Seconds to give you: G04 P5 (a 5 second delay).

Please look at the third attachment. These are the seconds selection from the drop down menu. Do we need more?

See attachments.

Here is the first cut on the Pause interface (attachment).

You select a drawing object with multiple passes set.

If you want the job to pause between each pass, check the checkbox and select how many seconds.

Question: how long will someone want to pause? A drop down will be simple to select but the seconds are fixed. A text box will allow one to enter any pause time but is not as simple as a drop down list.

Attached is a test file using a 3 second pause when burning a circle with 4 passes.

Paul has to add the G4 command to the Grbl parsing database, but for now, you can switch into No G-code Parsing mode (see attachment) and manually add your Pause commands. I'll design an interface so you can specify this and have BCL automatically add it.

The attached .nc file has the pause after each pass of the circle. What other situations would users need to insert a pause?

You are correct. I initially read the format for another CNC version of g-code. Grbl follows the linuxCNC model which shows as you have stated.

Great news, Ralph. Any chance the laser could also be Paused and then restarted from the stop point?
Not to add to your workload or anything.  :o

I will implement Dwell which is a Pause for nn seconds. Looks like this: G04 P500 ( pause 1/2 second )

1.8.5c is now released:

1. Immediate laser stop when clicking Stop buttons.

2. Laser tools: when a laser tool folder is selected, if there are any laser tools that have the Z Axis drop checkbox checked, the checkbox background color will change to light green. This will tell you that at least one laser tool has this feature selected. If you don't have a Z axis stepper motor on your laser, with the Z axis drop checked, your laser head may appear to stop or pause with multiple passes. This is because the z axis stepper commands are being sent to your laser machine but there is no Z stepper.

Scale is a CAD feature, like drawing a Line or creating a circle, etc. I don't have any plans to turn BCL into a CAD program, since BCL is a CAM program. That would be (1) re-inventing the wheel and (2) would be a massive, repeat, massive amount of work.

However, due to unique placement requirements, Text drawing objects can be created inside BCL and you can scale them. In ver 2.0 you will be able to do the same for Image objects. But those two drawing objects have precise placement requirements so there was an exception to adding scale capability to them, but that's it. No other drawing objects will get CAD features (Splines for example).

You can zoom in BCL (as you said) but you can't scale. To scale, you have to make that edit in your CAD program.

3D Printer Software / Re: 3D printer x/y steps per mm
« on: June 17, 2017, 04:43:51 PM »
I had to set a high value for my Z steppers on my 3D printer frame converted to a laser machine. The Z axis definitely wasn't 80 like the X and Y steppers are. I measured the Z axis travel to verify my setting was correct. Put some tape on where the z axis bracket was and sent a g-code command to move the Z axis up 10mm and then measured. I finally got the right setting and tested a range of mm distances: all came out perfect.

Wild.bill helped me with this setup and configuration process!!

Any Idea why all my prints load bigger in bencut then they are in all the cad programs?

They really don't load bigger. I have one word: scale. You have a zoom feature to adjust the size of your drawing on your BCL material canvas. Do you zoom in and out?

Look at the units scale in your CAD program. The height and width of your drawing is the same. The scale is just different in the software program you are using.

>Well, I at least figured out the crashing problem.  Bencut does not like to load from a usb stick.

What version of BCL are you uisng? 1.8.4? Ver 1.8.5 will load dxf files from a USB drive.

I hate to say it, but many have problems exporting dxf files from Adobe.

Does anyone have any suggestions on using another software to do dxf file exporting?

converted it to splines and now it causes bcl to crash.  Attaching a copy of the dxf.  I obviously did something wrong but have no idea what.

How about listing the steps leading up to your crash? Then I can try and reproduce it. Currently both George and I cannot get BCL to crash loading your bird1.dxf file.

BTW did you review the trouble shooting items listed in this thread:,861.0.html

Especially item (9)? The .NET Framework?

bird1.dxf loaded fine into my BCL software.

See attachments.

The size of the drawing is very large, too large. You need to scale it down to a reasonable size and one that you can burn on your laser machine. Look at the tab square in my attachment. That's my 12x12 inch work area. You can easily see how big your drawing object is.

In QCAD, the three units of measurements are not set correctly. You have metric and Imperial. You need to pick one and make them all the same. Don't mix them.
