Questions & Answers
The screw has four thread starts that are spaced two millimeters apart. It has a pitch of eight millimeters. During one revolution of the nut, the driven part moves eight millimeters.
The edges of my order measured 40mm from the bottom to the top (excluding the 22mm ring).
A little over 300mm of thread on mine the thread doesn't exit the motor like some, it's part of the shaft of the motor.
However, my nuts were missing, and I did not have a working motor. They were sent back to me.

Although I have several 3D printers, including 5 Select Minis that I mostly keep stock, I tried the lead screw upgrade just to see what it was like. It works great and is a fairly straightforward It saves time and effort since there is no need to use a coupler instead of the integrated lead screw. In addition to the nut shown in the product picture, we included it as well. If you will use a Dremel or similar rotary tool to cut the lead screw, make sure you have one. Among the many features it includes is the cable that connects directly to the motor and the Z-switch Interestingly there is a wire that is a bit long, but that should be expected when it is an upgrade product intended for general use and not specifically for If you're not going to mess with that, you can invert the direction by entering "M562 Z" after saving that, and sending "M500" back afterwards. If those two commands don't work, then you can try turning the printer off and back on again. Changing the direction of a motor can be achieved using only one of these methods, The two wires can either be swapped physically or by using the G-cable The commands are in code format.
Ensure that either 400 or 200 steps per unit (mm) are selected. Using "M92 Z400" or "M92 Z200" followed by "M500" is the way to go. There is a difference in the type of stepper driver on your mainboard based on whether it is 1/16th stepping (400) or 1/8th stepping (200). Here are some considerations to help you choose the value This is 1. * Send command "M503" to 2. Among the things to look for are The number of steps per unit is I'm writing about the M92 We are looking for a Y93 model. In the year 2000, Z1097 was issued. The E97 code is 50. I have typed 00"
Or I have typed "M92 X46. ". The number 50 is 46. I am 50 Z548, who has no middle name. The E48 code is 75. Z1097 to 50''
. The 50" in the first example above correspond to the Z steps per millimeter*"Z548," respectively. In the second example above, 90 steps per mm are applied, so 75 steps per mm are applied if the current value is "Z1097. ". Using "M92 Z400" and then "M500" is recommended for "50". When the current value is "Z548. ", then the current value is "Z558. ". If the 75" is used, you should use the Z200, followed by the 500. (You may have to cycle the power before the change takes effect. )
Now I have to resist the urge to upgrade a couple of the other Select Minis because else I will be posting advice about troubleshooting. As I already have an 8mm threaded rod on my original Robo3D R1, I'd like to use two of these to upgrade it.
The MP Select Mini v2 from Monoprice works perfectly with this product. In order to replace this old Z-drive, I bought this product The threaded rod of the MP Select Mini v2 from Monoprice is threaded. It was included with the carriage, and the brass nut shown in the product picture were included with the cable/wire. You will need a Dremel tool to cut the lead screw to length, and to remove the old nut from It still helps to keep the bolt holder as flush as possible, so I cut it off. Next, I used a drill bit to make a hole to allow the brass nut to slide in. My drill bit was a bit too large, so I drilled it a bit smaller and then reassembled everything to ensure it was Once the nut was mounted, I disassembled it again and completed the mounting process. Additionally 4 small holes were drilled and 4xM3 screws were used to keep it in place. Among the many features it includes is the cable that connects directly to the motor and the Z-switch I've swapped the middle wires on the mainboard. The black and red wires are already swapped, but I'm going to replace them with black and red. You'll also probably have to swap the outer (black/red) wires. Whenever I plugged it in, it made a really loud noise, and I learned that I had to swap the outer two wires after a bit of Googling.

My monoprice mini came with a Z axis, so I decided to use this as a replacement. I trimmed the height with the Dremel to fit perfectly (Thanks 2) From the rod and printing out the mounting bracket that's needed. As a result, I was able to get a significant improvement in the print finish on the Z axis, as well as eliminate almost all wobble. I was relieved to see that the motor itself came well packaged and included the brass motor nut, which I had been concerned would not be included. Overall, this is a great looking and functional web site. It was a relatively easy upgrade to the printer that was worth the cost.
There is an X-shaped hole in the ground It is believed that some point the z-axis gantry was redesigned so that screws were no longer needed to ensure its sturdiness An axis rod controls the movement of the axis. As a substitute, perhaps a press release would be helpful A plastic housing that formed a part of the gantry itself was used to hold the fit nut. This new motor guide I had to cut off and drill holes for, so I had to cut those two pieces and drill holes. It took a while, but in the end it worked out. Please proceed as normal with the rest of the installation guide (USWaterRockets, thank you for the guide!) However, I did run into a problem where the motor was reversed, but a simple M562 command resolved it. In addition to being more stable and accurate with this modification, my printer is more stable now as well. I do not have any complaints to make.
As a result of trimming the lead screw, I installed it, and it has been a delightful product. At , I was able to print successfully. This picture shows the 04mm layer height (see image). This item comes with a wiring harness and a nut. My only complaint is the packaging was not great, but I have spoken at length with the seller and they are working on it so there will be no issues in the future. It has been a pleasure to deal with and receive feedback from the seller. In the near future, I will put these to use!.
