I explain what the different settings do and help you figure out how to find and set the most important ones on your CNC machine by using the Universal Gcode sender (UGS). I show you how to calculate your machines step per millimeter (step/mm) by using your stepper motors steps per revolution (step/rev) in the GRBL code and measure in "real life" how far the axis goes. Hope you like this step by step tutorial.

Hello, while processing the g-code file I created with UGS in CNC, the CNC axes go to the place they need to go very fast when the carving work of a point is finished and trying to go to a different point (idle acceleration), which causes tooth skipping and the coordinate is distorted. I wonder if I need to adjust the grbl settings or the g-code file to reduce the speed of the axes in these transitions (idle speed).

[@eugenkrause5556]

Is acceleration that slow really necessary? I have not yet set but I'm wondering if setting mine to 200 would be bad. It's a 4mm pitch per rotation lead screw, and if I stall the motor, even at full speed the weight of the gantry can't move that lead screw.

Hello, I have built a CNC plasma cutter (MPCNC with GRBL control) and also use it with the Universal Gcode Sende program, but I have the following problem: The file has a length of 100mm, for example, but in reality it cuts me out to 300mm approx. All values in UGS are converted to mm (G21). What could be the reason for this and how can I correct this error? Please send me your feedback as soon as possible! Best regards Tobias

[@WillysGarageNorway]

Hi, the only thing I could think of is that you might have your settings, mm per rev, wrong

[@WillysGarageNorway]

Check how far it moves when you tell it to move 10mm in joging function in UGS, measure how far the axis travels in real life. If it moves to short or long, you have to check over your travel settings to make the axis travels the lenght you ask it to travel

Thanks , but when i try to change ($101=400) the stepper make a high noise and not moving, why ? My stepoer nema 23 ... 2A Thanks

[@WillysGarageNorway]

That means 400 steps per mm. Does your stepper have 400 steps per revolution? anyway you have to make these settings smaler when doing that.: $110=2000.000 $111=2000.000 $112=2000.000

Hi i'm working on DIY cnc router project but i have a problem with lead screw or ball screw it's expensive man i spent about 650$ for stepper Nema 34 and other stuff The question is Do you think if i use a belt my machine will be fast or what ??

[@WillysGarageNorway]

Eng.Mudar A I dont think the machine would be any faster with belts. Belts are prone to wear and tear, they will slack and start missing steps and stuff. With the nema32 And 23 I would recommend going for some ball screws even if they are expencive. You can also do lead screws like me. Belts would not cut it, sorry

[@WillysGarageNorway]

Hi and thanks :) You can calculate this value somewhat, but i depends on what drivers, steppers and PSU you have and use. So it's recommended that you increase this value until your stepper motor stalls and then decrease the value about 10-20%. This is so your system doesn't run on 100 % all the time :-) Did this answer what your question was about?

Hello sir I am using nema23 with tb6600 drive with 24 volt 10 amp, but with 32 micro stepping my motor rpm is very low around 30 or i change it into 1micro stepping then its rpm is around 150 with vibration I am trying to increase rpm of my stepper motor with smooth running Please help me....

[@WillysGarageNorway]

Tushar Gajbhiye Hi sir, it sounds like you have to change the $100 $101 and $102 setting on the Arduino. This setting changes when you change the microstepping on a stepper motor. If you have a 0,9 degree motor and use full microstepping (fullstep) your stepper must have 400 steps per revolution. Then if your leadscrew travels 2 mm per revolution this value should be sett to 200. That means that the stepper motor travels half a revolution for the cnc axis to travel 1 mm.

[@tushargajbhiye6487]

Hello sir, My motor have 1.8 degre & if i change $100,$101 and $102 setting more than 300 value then my motor stop rotating and make loud noise and after noise decree then motor little rotate and stop

[@WillysGarageNorway]

Tushar Gajbhiye do you use a leadscrew or belts?

[@tushargajbhiye6487]

Sir, I am using Ball screw Dia 12 x 4 Pitch

[@WillysGarageNorway]

Tushar Gajbhiye With a pitch of 4mm, that means the ball screw moves the axis 4mm/revolution. In the GRBL you want to input the step/mm. You have a 1.8 degree stepper wich needs 200 step/revolution. That means in fullstep mode: (200step/4mm)=50step/mm In half step mode: (200step/4mm*2)=100step/mm So, first of try to put $100-102 setting in fullstep mode to 50step/mm and test the machine

I tried too much to start building my cnc plotter but get depressed when question like these starts arising in my mind like - How do I set the zero position ? Direction of movement ? How do I calibrate ? What dimensions to choose and how to modify software part accordingly. Today morning I came to your GRBL config video and got some hope but still I am in a discomfort zone to start building my own cnc plotter. Why don't come with a simple video for beginner like me ? So many thanks.

what about setting soft limits and home?

[@WillysGarageNorway]

Have you done it?

[@ch3no2freak]

@@WillysGarageNorway I set all the speeds and did the calculations to figure out travel per step just like you did it. Huge help by the way

[@user-gy9hg8tv8b]

is this setting written by me ? or it's written by the same program?

[@WillysGarageNorway]

majick talent What program do you use? This settings are written in the GRBL code for the Arduino

[@user-gy9hg8tv8b]

WillysGarageNorway I use grbl controller or universal Gcode sender ...I don't know how can I setting this programs 😣......can you help me ? Please 🌿🌹🌿

[@WillysGarageNorway]

majick talent In this video I explain how you figure out and adjust the GRBL settings using the universal gcode sender. Hope it helps you

[@user-gy9hg8tv8b]

WillysGarageNorway I hope that too .... thank you for evry thing...

Hi, friend!! Excelent tutorial!! Just one question: why my Arduino don't save the parameters? I'm using grbl controller 3.6.1.

[@WillysGarageNorway]

TreCe Robotics Hi and thanks. Doesn't it save setting when you change it in UGS?

[@keith5675]

WillysGarageNorway Yes, right. The UGS don't save the changes. I think that is the EEPROM of ARDUINO or my Arduino is wrong. The tb6560 is good.

Maathav Rajan Hi, what do you mean? :)

Now it's ok thanks 👍👍

[@MohamedAmineBIDA]

Thanks Mr Willy,that's very helpful as always,I have question about the values of $110-$112,how would you know the values to set ? is it based on trying or based on calculation?

[@WillysGarageNorway]

Mohamed Amine BIDA Thanks again. You can increase gradualy 110-112 after you have found the step/mm (100-102). Increase it until the stepper «stalls» or you dont want it to go any faster. Then you can decrease it 10-20% to perserve your steppers. The same goes for the acceleration setting :-) Good luck and appreciate the feedback ;)

[@MohamedAmineBIDA]

thank you
