Students have to learn how to challenge themselves. Pushing yourself to the best of your ability is the best reward a student can give themselves. A student needs to set their mind on attaining the ultimate prize a good education with honors that makes them stand out. A student should be able to maintain the gusto throughout their student’s life. A student needs to have the bigger picture of what they tend to attain within a specified period. It is advisable that each student develops a long-term goal. The short-term goals should be in line with the long-term plan. Short-term goals help a student understand when they have missed on attaining a particular objective. If one fails in the short term, they will fail in the long run.

The best essay services reviews are the host of a paper writing service provider that assists students with academic papers. A wise student comes up with a plan of how to balance every aspect of their life. Like any human being, their purpose is not only academic. A student needs to develop the social, economic, and religious aspects of their life as well. A student needs to get inspired or rather they will get expired. Goals help a student live with a purpose.

We have put together bundles packs for some of more popular items. These are a great way to get all the parts needed without having to over buy on screws and etc.

Currently available are:

- V-Slot 20mm Gantry Bundle

- V-Slot 100mm Gantry Bundle

- V-Slot Gantry Bundle (Standard V-Slot Gantry Plate)

More to come soon!

Check them out at:

We received some Thrust Bearings to test. 

Dimensions are:

OD:  16mm

ID:   8mm

Height:  5mm

They fit into our Plates and Lead Screws perfectly:

They work great and will definitely be a useful addition to our inventory. Keep an eye out for them on the Maker Store web site soon.

Some more photos of the Arduino Uno CNC Connector for GRBL:

Arduino Uno CNC Connector PCBs arrived today .. so far they look good. Now to get soldering and testing! 

Below is a simple setup for testing or driving a single stepper motor. All that is required is:

1. Stepper motor (NEMA17 or NEMA23 work well)
2. Stepper driver (M335 works with a wide range of steppers)
3. Some hook-up wire
4. Power supply to suit your stepper.
5. Stepper Motor Pulse Generator

Connect it all up as per the image below:

And you get:

This Stepper Pulse Generator has an Enable/Disable button, as well as a Direction Button. The potentiometer controls the speed of the stepper. The M335 Stepper Driver can handle Steppers up to 3.5 amps and has plenty of grunt.

This simple setup can be used for a ton of application and builds, from camera sliders to robotic actuators!

Awesome and fun build!
Hi everyone, just a quick note to let every know that the following are now available at Maker Store:



STEPPER DRIVER - M335 - 0.5-3.5A 12-30VDC

Stay tuned, we have more exciting products coming soon!

For this post we will be making a simple gantry to run on a piece of 2040 v-slot. 

Parts needed are:
- 1 x 100mm V-Slot Gantry Plate 

- 4 x Solid D Wheels

- 4 x 25mm Low Profile Screws

- 4 x Precision Shims

- 4 x Nylon Lock Nuts

- 2 x 6.35mm (1/4") Spacers

- 2 x Eccentric Spacers

Tools needed:

- 3mm Allen Key

- 8mm Spanner

- 10mm Spanner

We will use a 100mm Gantry Plate, but any size will do as long as it fits with the v-slot profile. You can also use either the v-slot solid or V wheels.

Before starting, take a look at the exploded view below:1. Make sure to have identified the correct holes in the Gantry Plate for the screws to go through. In this example it is the middle of the set of 3 holes. On one side the holes are Ø5mm, these are for the 6.35mm spacers. On the other side the holes are Ø7.2mm, these are for the eccentric spacers (see exploded view above).

2. Push the screw through on one side. On the other slide on in the following order and tighten with Allen key and spanner:

- 6.35mm spacer

- Precision Shim

- D Wheel- Nut

3. One the other end push the screw through and then slide on in the following order order and hand tighten:

- Eccentric Spacer

- Precision Shim

- D Wheel

- Nut

4. Repeat #2 and #3 so you have all 4 wheels on and hand tight.

5. Roll the gantry on to the V-Slot - the Eccentric Spacers on one side and the 6.35mm Spacers on the other. See image below:
6. Now to tighten and remove any slack. Using a 10mm spanner turn the Eccentric Spacer until the D Wheel is seated in the V-Slot. Make sure it is not too tight and that it can travel smoothly on the V-Slot. When you have got the adjustment to where you want, tighten the Lock Nut using the Allen Key and 8mm Spanner. Repeat with other Eccentric Spacer.

7. Test the smoothness by moving the Gantry up and down the V-Slot. If motion is hard or jerky, loosen the eccentrics (#6) and re-test. If motion is smooth then make sure everything is tight and test again.

8. All done!

This is the basic construction of a V-Slot Gantry Plate motion system. Of course, like all our build, this can be modified to suit many other configurations. For instance:

- The height of the gantry can be increased by using longer screws and longer/additional spacers. 

- The width of the gantry can be changed to suit 2020, 2040 or 2080 V-slot profiles by using the appropriate gantry plate.

- The 2 gantry plates can be used to add stability (see image below):


Maker Store stocks 3 main type of nuts: Lock Nut, Hex Nut and Jam Nut.

Below is an image showing the 3 types:

Lock Nut:

Used when you do not want the nut to come loose. These are used with out wheel kits and for most builds. The nylon insert grips the screw thread and resists loosening.

Hex Nut:

Similar to a lock nut but without the nylon insert. For general purpose use where loosening is not a critical concern.

Jam Nut:

Thinner than both the lock and hex nuts. These are supplied with the Anti-Backlash Nutblocks and are used to fasten the grub screw into place. Can be used when a thin nut is required.


Trapezoidal threads are defined as follows by ISO standards:


where Tr designates a trapezoidal thread, 8 is the nominal diameter in millimeters, and 8 is the pitch in millimeters. When there is no suffix it is a single start thread. If there is a suffix then the value after the multiplication sign is the lead and the value in the parentheses is the pitch. For example:


would denoted 4 starts (as the lead divided by the pitch is 4), 8mm diameter, 8mm lead and 2mm pitch.
