This is great. Do you have a diagram for pin to pin connectivity?

Thanks will do

Yup. For now

I would like to go to LinuxCNC in the future

Hi Dan,

I am in the process of building my CRP4848 using the same electronics and I would like to hear more about this plugin and wire connection on the HY VFD. How to connect the RS485 on the VFD...

Good Job man. I am planning to buy the Bolton ZX45 next year and start on the CNC conversion, Belt drive and pneumatic tool changer. Will follow your thread closely

Finally After a year of ups and downs, work and money issue my CNC was born. Here is a photo

And there is no racking with a middle screw

Hi,
I am new in this so please bare with me :)

I just built my CNC router and I have installed my home switches on the 3 axises in series (NC). I have a Xylotex 4 axis driver board and I...

I started assembling the machine yesterday evening. I did the main frame. thought about the way to properly put the extrusions together. I came up with a way that probably right. Some scrap wood cut...

Started on cutting the extrusion yesterday, Very good experience actually. I thought it will be so much pain since I am cutting with my Bosch table saw. However, this Diablo Blade is very good that...

Long time since I posted anything in the thread. I was fetching the materials from here and there. Got the extrusion safe at home, The MDF sheets that will be used as templates before working with...

I was thinking the same but in a different way :) may be if I widened the adapter that connects the nut to the gantry it will make a difference. I will be trying different ideas during the build if...

That's a relief. I have a lot of different sizes too. M8, M6, M5, M4 with flat heads, socket and Button with different length too. So I guess am good :) Time to start on collecting info about the...

As the title, screws mmmmmm I didn't think that I will be buying screws for $100. Please guys tell me that I didn't get screwed and it is normal when you buy 10 or 15 packages of 50 and 100 different...

I am now stuck in a very stupid donkey work, calculating the number and size of screws. Do you guys have a a way to just buy screws in bulks. Is there like a standard or assorted collection that I...

Thanks for sharing this video, gave me more confidence. What do you think about the design and the extrusion used?

Thanks CarveOne I will check this out for more knowledge

From the isometric photo down with the bed hidden you see that I can support the frame with any number of extrusion needed. so the problem of racking I guess is in the rigidity of the frame itself...

I guess I will try the middle screw and see how it will work. If it troubled me I will just buy a new screw and a piece of extrusion and make it dual screws. Good that you mentioned that we need two...

Good to know that. Do you have a link or can you give more details about the cable and pulley system. This is the first time to hear about it.

I am guessing that one home switch will be enough either on the left or the right screw and that's my guess. I saw alot of center screws cutting 3/8 aluminium and using 1/2" end mills. They are also...

pippin88,

very comprehensive feedback. Thanks. The design concept below is very versatile. If you look below you will find that the Y-Axis is separate on a thick 40-4080 piece of extrusion. Adding...

Here is the extrusion selection for each part of Model 1100X. May be this will define more why I went with the design below.

The Main Frame: (40-4080 & 40-4012)

Yes. I see that a lot of members here are not fan of single middle screw. I understand that having 2 screws will be better. but according to my design here the gantry is heavy enough to put pressure...

Thanks for your input pippin88. I based my design on other designs, which I saw working and all were made with one central screw. I agree that 2 screws will for sure be better but the single middle...

I understand what you are saying. the connection of the gantry with the bend factor of the extrusion itself might make a problem in the movement of the Y-axis back and forth. According to my...

I finally finished the design for the Model 1100X. Time to shop for some extrusions (nuts)

Here are some photos of the different views for the build. Feedback guys

I just got into the CNC world less than 2 month by buying my first Sherline CNC mill 2000. Sherline is really a great machine. However, it has it own limitation, from size to
spindle power. This...

I guess as a hobbyist, I don't need less than 0.005" or even 0.006" for my applications. But it is always good to work with and produce your own. Thanks LeeWay for your participation

Guys,

I was just wondering what is the acceptable tolerance for aluminium (i.e bow) that you can work with to make parts. For me for example I do my work, since I am a hobbyist and don't have...

Aha, Got ya. Thanks
