CNC Design and Manufacturing – Issues with GRBL and GCode Senders

Please visit www.DIY3DTech.com for more information on this and many other projects! As in this episode we will be talking about issue with the CNC, GRBL and GRBL Controler. Maybe you can help me figure this out ūüôā

Dwell Issue with GRBL Using a Laser

Appears there is a delay in GRBL (v0.9) with the issue of the M03 spindle direction command GRBL will delay its movement to allow time for the spindle to spin down, reverse and spin back up.  So instead of using M03/M04 for rapids, we have switched to using PWM (Pulse Width Modulation) using S0 to set to the lowest level (basically off) and S1000 for full power.

Timelapse of the Probotix Fireball v90 running Chillipepper and GRBL on Arduino


So here is the time lapse video of the Probitix Fireball v90 CNC router running Chilipeppr via Arduino and GRBL software. Also in the video we have the string settings which we are using for garble so if you want to try the same this should provide reference point.

Update to the Probotix Fireball v90 CNC conversion to GRBL


So we’ve now got the¬†Probiotix¬†Fireball V 90 running with all the major GRBL¬†front ends including Chilipeppr, GCode sender and Easel. We have noticed a couple strange things, one of them being GRBL¬†wants to flip the X and Y axis. This is in both the nature (i.e. X becomes Y and Y becomes X) and direction, to correct this we’ve had to use change the GRBL string $3=3 (inverting both x & y) to mask the directions of each access. With regards to the X and Y axis flip, we have tried inverting the wiring to reverse them, however this only results in what appears to be a mirror image when cutting sort of like from the bottom up rather than the top-down. So to correct¬†for this we’ve just allowed the flip in axises¬†and simply changed the homing location and perspective of the material which seems to work just fine. Watching the video you can see we’ve cut out several rather complex shapes without issue. However one of the interesting things you will¬†notice in the video, there still is one part abandoning the material and this was caused by “user error”, as I forgotten and unplug the laptop causing¬†the battery run out while sending G code, Oops. However other then several minor challenges overall the conversion process has gone rather easily, And in fact has been quite a bit of fun as my goal with all this was to create a simpler workflow and both Easel and Chilipeppr filled this goal. However I must say with regards to just GCode sender the jury’s a bit out as ¬†I’m concerned as how effective that is, (because it is quirky compared to others) but hey it’s still early in the game. So look for some more updates soon Will be doing the final install of the Arduino on top of the Probotix¬†driver box an the¬†final wiring to complete this project so once that’s done I will do the video on that as well along with¬†a video on the configuration file for¬†GRBL itself.

Wiring the Arduino & GRBL for the Probotix Fireball v90


In this episode we going to the shop and wire in our Arduino with GRBL into the Probotix Fireball V 90 CNC router. Again this is a rather simple build in we will solder the pins from the DB-25 parallel port connector into the header pins of the Arduino and once this is completed we will be able to control the Probotix Fireball P90 CNC router via the free Gcode sender or an application such as ChilliPeper or Easel.

How to wire Arduino w/GRBL for Parallel Port Control


So in this episode we are going to look at wiring the¬†¬†Arduino¬†running¬†¬†GRBL¬†to a parallel port CNC machine control yet before you get too concerned this is actually a pretty simple project as what¬†we’re going to cover are the pinouts from the Arduino and¬†matching them up with the opinions of the standard parallel port again most of this is simple soldering to a DB 25 connector which we will plug into the parallel port.

Flashing an Arduino UNO with GRBL v0.9i for CNC Control


So we’ve been doing a lot of experimentation in the lab lately with motion control and one of the latest projects we’ve been working on is converting our Probotix¬†Fireball V 90 from parallel port control using Mach 3¬†to using GRBL¬†on the Arduino as a replacement. ¬†The reason for this is we want to take advantage of the many second-generation programs out there such as Easel¬†and others which streamline the workflow of the CNC process.¬†However one of the first challenges is getting GRBL¬†on your Arduino¬†itself and to do this we took a quick scan of the Internet and couldn’t find any good videos demonstrating how this process works, so the next step¬†was to create one of our¬†own and in this video we will show you how to flash the Arduino and¬†send commands to GRBL¬†and more importantly where to find all this in addition below we have placed the key URL links to what you will see in the video there so they are easy to find.
