I received my drivers and checked the schematic posted in this thread. I have redone the schematic with designations matching the board. As noted before the WARN LED circuit is not correct. Further I...

I have looked at the TB6600 datasheet to determine the max current that can be sourced by Vreg. without success. Has anyone found this out? The Haoyu schematic if done right should draw 15ma or so...

I just read the TB6600 data sheet and notice that max current to sink at Alert and MO pins is 1ma. Then I looked at the Haoyu circuit that lucas posted and they are lighting a LED with 8ma. I assume...

It looks like you have decided on these plug in drivers. You should look here before you order

SureStepr SD8825 Stepper driver

The TI 8825 can carry more current and these boards are made the...

Those are Nema 23 motor needing 2 amp per coil. The Pololu 4988 was designed for Nema 17 and is used mainly in 3D printers You would need heat sinks and a big fan and even with that they would...

I have done a Google search and looked at several TB6560 designs and most use a 5V regulator as this design does without any sequencing circuitry. The ST330 does have one odd thing. The reset pin has...

To use GRBL
1) Adafruit carries Arduino prototyping shields. Mount a 26pin IDC connector on the shield and wire it to the Arduino pins. Then make a ribbon cable 26 IDC to 25 pin DB (parallel port)...

The THB6064(TB6564) appears to have been discontinued, since is not on the Toshiba website. In the USA Mouser has the TB6600 in stock at $7.50. The Cinese TB6600 boards have no schematics so you do...

1) Are you using the TQ pin to lower current when system is idle.
2) You are using the pcb to press the TB6600 tightly against the heat sink. Over time will this heating of the pcb cause problems?...

By power supply sequencing, that the logic power is up before or at the same time as the motor power. The 5V regulator is on the board and is connected to motor power, so logic power and motor power...

Three solutions
1) Use the ST330 driver from SainSmart sold on Amazon for $17 each. You will also need a breakout board also available on Amazon for $23 Find a n older desk to computer with parallel...

These single driver boards using the TB6560 chip are available from Amazon for $16, so I ordered one. When it arrived I looked online for a circuit diagram with out finding one. In fact these...

Here is the schematic for my version of the Planet-CNC pcb. I started this layout based on a comment by PMinMo in this forum that the orientation of the 10 pin driver connector was such that a 180...

I paid $9.62 ea, but they are now out. They do have 72, SLA7067M at $12. ea.

I see that Mouser has TB6560 at $4. ea and, depending on your motor type, that may be a better choice. I still like the...

Opto Isolation: Maybe you are not worried about an old desktop computer, but if the CNC electronics, say the CNC USB Motion Controller, is plugged into my expensive laptop, hopefully, the isolation...

I have a prototype opto isolated driver on Batchpcb. The BOM and (circuit soon) are on my blog (cncrouterbuild.blogspot.com.) As soon as the board is tested I will post results here.

If you are determined to make the mount, why not get a HDPE breadboard and cut it out with a coping saw. You can make one similar to Bluumax. HDPE can be worked with woodwooking tools.

I went back and looked at schematics in the first post of this thread. The schematic shows a common ground which means the driver chip and the parallel port have the same ground, so what is the point...

Few comments
1) Grbl directly interprets GCode and CNC USB Controller by Planet CNC does not. You need both the PC program and the 18F4550 controller, since the PC code converts the GCode to an...

I am in the process of designing and building a CNC router:

Design Features:

I have found another diode which I would prefer using, EGP20A by Vishay. This a 2A diode with a Trr=50nsec. The datasheet does not say "soft-recovery";however, the recovery curve looks almost...

Question for Mariss Freimanis concerning TB6560 diode:
I have looked for this soft recovery diode and the only one I can find so far is the UF5401.
This diode has a Trr of 50nsec and says soft...

The adjustable versions, LM317, are listed as differential voltage, but the 78(L)05 is referenced to ground. For the 7805 it is 30V.

There is a LM317HV which has a 60V differential which could be...

I am presently designing TB6560 single driver pcb. I have noticed several circuits on this thread using a 78L05 regulator. If all the 78L05 is doing is supplying the TB6560, 3 to 5ma, you are all...
