Re: Z axis faster than xy axis
actually, I've discovered something.in marlin 1.1.6, you can adjust max feedrate, max acceleration, etc, and feedrate in lcd. but there's something strange.I can insert max os 600 mm/m(I guess it's in...

okay, so I've noticed one thing.I've insert 600mm/m in homing feedrate.if I only send an individual axis to be homed, it goes normal, but if i insert to xy homing together, y goes normal at his...

The motor data I was after was the rated current, inductance and holding torque of the X and Y stepper motors, not the firmware settings. Anyway, if your steps/mm with full stepping is as high as 141,...

There's RADDS running well on RRF. The TMC2100 is even quieter on an 32bit board than on 8bit. Why not use a single RAPS128 driver for two steppers, they are quiet too and have plenty of power. Z axis...

Thanx for that info... The more I look into this the more I think I may bite the bullet and go for a Duet3d Wifi soon... Well around end of May kinda soon as they are so $$$

I'll buy new stronger motors and see what happens, but thanks a lot for your help!

Hello to everybody, yesterday I try to change GRBL config because z-axis of my cnc must stay in tension to withstand weight of axis. I set $1=255 (Step idle delay, milliseconds). 255 = always on....

Stronger motors won't help if problem is that your printer design uses a very high steps per mm and therefore the motors have to rotate very fast. If you can't reduce the steps/mm then you need low...

Ehm.... Anyone have an idea? I have block all the project because I do not want to break anything ::o
View ArticleRe: Strange situation with stepper motor
Keeping the motor ON all the time the motor will heat up and get very HOT. Use a motor brake or mechanism to hold axis. A worn drive or counter-balance could work :S
View ArticleWhich motor to choose? 1.8deg 59Ncm vs 0.9deg 46 Ncm
So, I'm building my second printer based on the AM8 plans on Thingiverse. I'm thinking of buying either these 0.9deg 46Ncm motors (here) or these 1.8deg 59Ncm motors (here). My current printer uses...
View ArticleRe: Which motor to choose? 1.8deg 59Ncm vs 0.9deg 46 Ncm
stick with 1.8 for non delta type machines Overly simplified, using 0.9 does give you more theoretical resolution... but at the cost of half your max speed (twice as many steps/mm and you start to run...

Ah okay, thank you for the information. 1.8 it is then!

Hi. I have recently incorporated TCM2208 drivers to my machine. And I have found this: 12V is not enough. Steppers were weak, loosing steps and in standstill, they screamed in StealthChop2 mode. Then...
View ArticleRe: Great new SiLentStepStick TMC2208 is not silent ;(
It would be helpful to know what motors were used by @abuharsky and @kolin. They may have been low current high inductance motors, which are not suitable for operation with a 12V supply anyway. Hint:...

Can i run DRV8825 with this NEMA motor :S
Hi family , i want buy a stepper motor Nema 17 17HS4401 21008717HS4401datasheetscaled.jpg The current per phase is 1.7A i want know if i can run it with DRV8825 driver with any problem or burn the...

A general rule about steppers is: run them at ~80% of their rated amperage. In your case it is 1.36A. The DRV8825 will have no problems with it. Cooling the drivers with a fan is mandatory.

An other 2 question , if the DRV8825 is in power and the motor is connected with it and its not running ,So the driver will be heated or no ?? because the motor is not running, The fan must be turned...
