Re: 3 Axis Stepper Control

Dear Mr Enamul,

Thanks for the posted code.
But sorry, its not working, no out put from RB0 to RB3.
I have connected the potentiometer as advised by you at AN0 pin2 of 877A
I have also connected 4 LEDs at MOSFET output, nothing is showing.
Please help.

Thanks
With best regards

Re: 3 Axis Stepper Control

Dear Mr Bercioiu, Thanks for your reply. Yes we didn't found the exact data of my Motor on net. It a refurbished Motor. Please see the post dated "Sat Dec 08, 2012 10:01 pm" by Mr Enamul for Motor specification. We assume it is 5.2V and 1.5Amp. Actually i don't want to add a high value like more tha...

Re: 3 Axis Stepper Control

Dear Mr Enamu and Mr Bercioiu, HAPPY NEW YEAR. Thanks for the suggestion and guidance. I want to know what will be the Control Freq, % of Duty Cycle (MAX ON TIME and OFF TIME)? How Control the Speed by adding a Pot in to AN0 input. Can we add a Voltage and Current sense from the Motor and control th...

Re: 3 Axis Stepper Control

Dear Mr Enamul, I wish all of the Flowcode Team and you "HAPPY NEW YEAR". Thanks for the code. I test the code found, 1: To START the Motor i have to press the switch and hold, when i release the switch motor STOPs. It should be like this, In 1st press the Motor should START running and in 2nd press...

Re: 3 Axis Stepper Control

Dear Mr Enamul, Thanks for the reply and query. " You mean you are driving the motor and MOSFET both using 15V " Actually Motor Common is connected to 24V rail and A,A1,B,B1 of motor terminal is connected to MOSFET directly without any current limiting resistors. " I think you haven't used any regul...

Re: 3 Axis Stepper Control

Dear Mr Enamul, Thank God, the motor start running after changing the Delay value from 1Sec to 50uSec. The MOSFET is still Hot enough at 15V, i am planning to change the MOSFET.

Re: 3 Axis Stepper Control

Dear Mr bercioiu,

I have studied the Schematics provided the links by you. Thanks.
In OS3schematic.pdf control is from parallel port. right?
Have you done this project? If yes, what interface software you are using to control the CNC Machine, kindly tell me.

Thanks

Re: 3 Axis Stepper Control

Dear Mr bercioiu,

Thanks for your reply on my thread and suggesting. Yes my Transformer has arrived, sorry i have not tested yet.
I will search the suggested MOSFET IRLZ44 locally and let you know after that.
I will post the result of my project after testing.

Re: AVR using TRIAC

Dear Mr Enamul,

Thanks for the schematics.
Please add more details of the Transformer used in both the designs.
If its a home made, wire gauge, core specification, turns and all the parameters are required.

Dear Mr Enamul,

Good Evening.
In the sent code you have used 20MHz Crystal but in my hardware i have used a 4MHz crystal.
Shall i correct in the code 20MHZ to 4MHZ and HS to XT ?
Pl replay.

Re: 3 Axis Stepper Control

Or we write a simple code and test the Motor with CPU?

Re: 3 Axis Stepper Control

Dear Mr Enamul,

Thanks for the replay, If you are right each motor will draw 3A at maximum load so 9A is needed to drive 3 Motors.
So let me tell my supplier to increase the current to 10A. This will solve our problem.
What do you say?

Thanks
