I'm interested in making grbl cnc, so I'm watching several videos, but this one seems to be the best^^ I can feel the whole process at a glance~ Good video I'm very grateful to watch it again!

[@Bright8888]

Thank you MI, for providing the necessary links, especially for the Inkscape extension. I was able to complete the circuit part of the project and test it. The stepper motors and the servo work as expected (My Inkscape version: 0.91). You need to carry out one correction: At 6:38, the resistance is shown at top left corner as "1.6 Ohm". It should be 1.6 K Ohms.

[@MrInnovative]

oohh yes thanks to point this out

ohh thanks brother

[@pir869]

when you measured the resistance from one end to the wiper of the current control pot,did you measure 1k6 ohms or 1R6 ohms,as the meter looked to be set to 20k ohm position,while on screen has 1.6ohm,and i measure the pot end to end at 10K ohm,1.6ohm would be hard to find on such a large resistance track. Also,when you use Grbl controler,what steps per mm did you use,i had to input 5.8 steps/mm to get close to 1mm,while some people using cd/dvd steppers use 50-55 steps/mm,i'm new to the arduino cnc,but i'm a qualified electronics technician,hope you can clear up the pot and step issue for me,thanks.

MI thank you for this amazing tutorial. I have done everything as you have mentioned. It works well but there is an issue with the alignment of different parts of a g-code! The machine starts to draw the lines as it should. Somewhere in the middle of the drawing the lines on the X axis are moved by some offset. The drawing shown by the g-code uploader are ok but the result is as if some parts are moved by offset on x axis. I have tried different g-codes with no luck. If the gcode is a single pass of the pencil with no going up everything is ok. can you help me with that plz? I can share the photos of the results if it helps.

looks motion is not smooth off stepper motor on the threaded shaft , will u try by applying some lubrication on shaft..

[@mohammadsadeghebrahimi8256]

Thank you. I replaced the whole assembly of X Axis and it solved the issue. Seems like the stepper and the plastic which engages inside the thread were kind of worn or sth. Good luck man!

[@Jono6671]

Mohammad Sadegh Ebrahimi you must check the specifications of the motors etc you have, and anything else that needs power. When selecting a power supply (you might need multiple power supplies for different voltages) , make sure the volts is exactly what you need, (eg 5v, 12v, 24v) and once you know how much current your devices are going to pull MAX, (say 10A for instance), I would always select a slightly higher current PSU just in case, like 12A for example. It really depends on the equipment you have.

Hello Great video thank you for uploading it. From about 15 videos I looked at this was by far the most informative.. However I believe there is an error on 5:13 servo plugging. The servo should be connected not to +z Endstop, but to SpnEn. If you look at the inkscape zmotor routine at 12:44 you will se that the pen unp/down setting is connected to the 90 degree M3 instruction. I looked up in google what this M3 instruction is and it is Spin Enable (SpnEn). I am away on trip so it will be a couple days before I can verify this but I believ that may allow many users to have a functioning z drive.

Hi there, It has been a fantastic project and I enjoyed making it. Many thanks and Lots of good luck for your future projects. I have two questions, pls help asap. 1. my X axis is printing inverted (Which i resolved changing the stepper connection is there any solution within the software). 2. When i send M3 for servo up and M5 for servo down in UGS "commands" windown my servo on machine follow it correctly. (That means machine hardware and software are configured correctly) however when I am generating Gcodes with Inkscape 0.92.2 the servo found to be inverted, ie where it should print it is leaving blank and where it should not print it it printing. I gave closer look into my Gcode file and opened it in notepad I found inkscape is generating the wrong code (ie it is generating M3 for servo down and M5 for servo UP). So I changed MI GRBL servo controller settings ie for Servo UP M5, and Servo down M3. Now it is generating the correct code. Though my machine is working correctly and printing correctly but I thing there has to be a proper solution to these problems. Please advice.

[@MrInnovative]

1. yes you can do by changing some GRBL configuration please read the following github.com/grbl/grbl/wiki/Configuring-Grbl-v0.9#2--step-port-invert-maskbinary 2.Changing M5 or M3 from MI GRBL servo controller setting is the right way to do, or if you dont want to do this changes so you need to mount your servo by flipping 180 degree this also solves your problem, now you can judge which is the right and easy way :)

Hi I am using 12v 1A, but the motors seem like no enough power, and they generate a lot of heat. Why is that?

[@manvandog9796]

Your power supply needs to be able to support the combined current of all of your steppers. If you use 3 motors with a current draw of 2A each, your supply needs to be able to provide at least 6A. Try a more capable supply and see how that goes. The heating of the motors will be caused by the static spindle increasing resistance on the coils. If the spindle was moving this would be less evident

[@pawelkrawanski4249]

Imran Ahmed A4988 stepper motor can give you Max 2 amps with radiator and cooler. it's sufficient current for nema 17 stepper motors but for bigger ones it could be not enough.

[@learnbox3783]

What should I do for large size stepper motors driver?

[@pawelkrawanski4249]

First calculate what torque you need. Than Find proper stepper motor. There is many types that run under 2 amps (nema 17, nema 23 etc.). They ususally give 0,4 - 0,5 Nm torque but some more expensive models can give you even 1-2 Nm. Mind that with nema 17, 23 using threaded rods you can run realy heavy parts of your cnc machine. There are many examples on youtube. For machines that type, arduino + grbl + A4988 should be enough.If you need stepper motor that runs with current between 1,8 and 2,2 amps you should use DRV 8825 stepper motor driver. It's compatible with grbl shield for Arduino. For 3 amps AMIS-30543 30V 3A SPI. It's not compatible with grbl shield, but I you can connect it to arduino with wires.If you need reeeeeeaaaaaly big stepper motor with powerful torque for more serious purposes you should check for different drivers. For example - 5 Amps HY-DIV268N-5A based on TB6600. It won't run with Arduino ang grbl shield.But if you need big stepper motor (I mean STEPPER MOTOR (BIG ONE ;) ) with torque 80 Nm find some industrial stepper motors with proper drivers.

Bhai video me cnc shiled pe green, Nd orange red colour ke wires connect kiye he unka second end kaha pe connect he
