Hi All, Construction of my machine is going well (a router that can do about a 1/2 sheet of plywood). I have the Zaxis complete and am working on Y. My first...
how fast is the drill?? are you sure the alignment from end to end and thru the axis feednut/block is good. are you using bearings on each end? gerald ... ...
It is a variable speed drill, so I was able to ramp the speed up and see where things fell apart. I have bearings on both ends, and the alignment is good. The...
Hi, I see that you have received some advice over on the DIY list. I just want to mention that any speeds gain you get by going to a small TPI number will...
Yes, that's definitely a concern. I think I am going to go for 2TPI, but leave myself an "out". If it is too tough on the motor, my design can be pretty...
Hi, Using a timing pulley/toothed belt system to start with means you do not have to worry so much about shaft alignment and not at all about shaft couplings....
Unfortunately, I've already ordered my motor couplings :-( I'll give direct-drive a try, and if I have any problems, I know what to do. Pete ... you ... system...
Peter, You are not alone in the "whippy" problem. There is a know term for this called "wobble effect" . Even if you start with straight, hardened rod, it...
The "JGro" machine my friend and I built has 1/4" threaded rod 43" long in it. The design incorporates an anti-whip block to curb the tendency a bit. Simply a...
I would say go with the 2 start acme screw and reduce the amount of revs you have to make per inch of travel this should slow the whipping down. I read...
... soon. ... Matt, I suppose I went about it backwards. I bought the most expensive portion first though. Now I plan to build the router table outlined in the...
Hi, No, do not run 2 motors on the same drive output. If you want to run dual motor on an axis, get Mach2 and use the 'slaving' option, on a 4 axis drive. Jeff...
I lost power to my CNC yesterday! At first I thought it was the power supply, so I disconnected the motors from the board and found the power stays on. I dug...
Hi, I responded to the e-mail you sent over the weekend. Some things from the datasheet: Restrictions Do NOT adjust the Vref voltages with motors attached Do...
... Digitizing is creating a 3D model of some existing object by probing the surface with some instrument (ie a digitizing probe). Mach, TurboCNC, DeskCNC and...
I'm trying to wire limit switches to my XS-3525/8S-3 I'm using Mach 3 software and I'm getting a contant attive low on pin 11 and 12 with nothing wired to the...
Could the experts here help me with a motor decision: I'm looking for a dual-shaft nema-23 motor, to complete the Y-axis on a mini-mill CNC conversion. I'm...

Hi, It's ON-TOPIC as far as I'm concerned. If you are running slow, you will get the full torque that the 2.5A will allow. It is when you start picking up...
Jeff, This is just a quest to learn a little about IC's. I have a new Xylotex board that I recently bought and noticed that the IC's under the heat sink are...
The mystery IC under the heatsink is an Allegro 3977, and more info on that is here http://www.allegromicro.com/faq/3977faq.htm . And what I've found here, a...
Hi, Yes, it is the A3977SED from Allegro. No secret. A 5 wire motor will not work with the Xylotex drive. It is a unipolar motor or a 5-phase motor. I hope...
... drive. ... No, No. I would not do that. I have a home built unipolar drive that I built. I have my xylotex stuff in a box, put up until I complete my...
Thanks for a reply. I'll have to do some diagnosing... see how the (single-shaft) motor I have now does (260-280oz-in, 3.1a type), and weigh whether I need...
Hello Group: I ordered my 4 axis drive box and motors from Jeff last night. I plan to use IntelliCAD software for drawing the parts I need to make. I am...
Hi Barry, What sort of parts do you intend to make? Les ... -- No virus found in this outgoing message. Checked by AVG Free Edition. Version: 7.1.375 / Virus...
Hi Les: We make cameras. Really large cameras from wood and brass fittings. Some time we may change to a few aluminum pieces. For the most part the parts are...
Mach will import DXFs directly, this will save the cost of CAM software as you say your parts are all simple 2d. Mach is available as a free trial, so you...
